2. Tom Marley and Jennifer Griggs have recently started a marketing research firm in Jacksonville, Florida. They have contacted the Florida Democratic Party with a proposal to do allpolitical polling for the party. Since they have just started their company, the state party chairman is reluctant to sign a contract without some test of their accuracy. He has asked them todo a trial poll in a central Florida county known to have 60% registered Democratic Party voters. The poll itself had many questions. However, for the test of accuracy, only the proportionof registered Democrats was considered. Tom and Jennifer report back that from a random sample of 760 respondents, 395 were registered Democrats.

a.Determine the probability that such a random sample would result in 395 or fewer

Democrats in the sample.

b.Based on your calculations in part a, would you recommend that the Florida Democratic Party (or anyone else for that matter) contract with the Marley/Griggs marketing research firm?Explain your answer.

3. Micron Electronics makes personnel computers that are then sold directly over the phone and over the Internet. One of the most critical factors in the success of PC makers is how fastthey can turn their inventory of parts. Faster inventory turns means lower average inventory cost. Recently at a meeting, the VP of manufacturing said that there is no reason to continueoffering hard disk drives that have less than a 2.0 GB storage capacity since only 10% of Micron customers ask for the smaller hard disks. After much discussion and debate about theaccuracy of the VP’s figure, a sample of 100 orders from the past week’s sales was taken. This sample revealed 14 requests for drives with less than 2.0 GB capacity.

a.Determine the probability of finding 14 or more requests for hard disk drives with low storage capacity if the VP’s assertion is correct. Do you believe that the proportion ofcustomers requesting hard drives with low storage capacity is smaller than 0.10? Explain.

b.Suppose a second sample of 100 customers was selected. This sample again yielded 14 requests for less than a 2 GB drive. Combining this sample information with that in part a,what conclusion would you now reach regarding the VP’s 10% claim? Base your answer on probability.

4. Agri-Beef, Inc. is a large Midwestern farming operation. The company has been a leader in employing statistical techniques in its business. Recently, John Goldberg, operationsmanager, requested that a random sample of cattle be selected and that these cattle be fed a special diet. The cattle were weighed before the start of the new feeding program and at theend of the feeding program. John wished to estimate the average daily weight gain for cattle on the new feed program. Two hundred cattle were tested,

with the following sample results: X = 1.2 pounds gain per day and S= 0.50 pounds gain per day.

a. Obtain a 95% confidence interval estimate for the true average daily weight gain.

b. Provide a 90% confidence interval estimate for the true average daily weight gain.

c. Discuss the difference between the two estimates found in parts a and b, and indicate the advantages and disadvantages of each.

d. John is considering adopting this new diet. However, the weight gain comes at a price. To feed 200 cows for one month, the diet would cost approximately \$1,000 more than theircurrent feed program. If the price of beef on the hoof has been close to \$0.20 a pound, would such a program be cost effective for Agri-Beef? Support your answer with calculations and statistical reasoning.

1. A major American pharmaceutical company has randomly sampled 14 customers who have had prescriptions for one of their new pain killing drugs for 2 months. There is concern thatthe drug may elevate the user’s heart rate. Each of the customers in the sample had his or her heart rate measured after using the drug for 1 week. All people in the sample had heart ratesof 55 prior to taking the drug. The following data were recorded for the 14 customers:

50 70 60 70 90 72 50

80 85 55 66 70 80 40

a. Suppose that you have just started working in the marketing department of the pharmaceutical company. You were given the following instructions: “Based on these sample dataconstruct a 90% confidence interval estimate for the true mean heart rate for the company’s drug customers. Interpret the estimate.” (Assume that heart rates are normally distributed.)

b. Referring to your answer in part a, could the estimate be applied to all potential drug customers? Explain why or why not.

c.Refer to your calculations in part a. Was the concern expressed justified? Justify your answer. If you conclude the average heart rate did not increase, determine the probability that asample mean at least as large as the one obtained in your sample could actually have been obtained.

9. Most major airlines allow passengers to carry two pieces of luggage (of a certain maximum size) onto the plane. However, their studies show that the more carry-on baggagepassengers have, the longer it takes the plane to unload and load passengers. One regional airline is considering changing its policy to allow only one carry-on per passenger. Before doingso, the airline decided to collect some data. Specifically, a random sample of 1,000 passengers was selected. Researchers observed the passengers and noted the number of bags eachperson carried on the plane. Out of the 1,000 passengers, 345 had more than one bag.

a. Based on this sample, develop and interpret a 95% confidence interval estimate for the proportion of the traveling population that would have been impacted had the “one-bag” limit been in effect. Discuss your result.

b. The domestic version of Boeing’s 747 has a capacity for 568 passengers.

Determine an interval estimate of the number of passengers you would expect to board the plane with more than one carry-on. Assume the plane is at its passenger capacity.

## Parametric and non parametric analyses | RES814 Quantitative Research Methods | Colorado Technical University

Part 1

A principal wants to determine if a new ACT preparation program is effective. The data are contained in the schools.sav data file. Open the schools.sav file in SPSS. Use SPSS to determine whether a significant improvement existed between student performance on ACT tests in 1993 (act93) and ACT tests in 1994 (act94). Assume that the same students were involved in 1993 and 1994 testing. (This requires a t-test. Review Chapter 10 of the Green & Salkind text for information on paired t-tests and reporting APA results interpretation and writing.)

Create a report that answers the principal’s question. Write these conclusions in formal APA results format. Include your SPSS output to support your conclusion.

Part 2

A pharmaceutical company wants to determine whether there is a need for a new medication based on the data in the electric.sav file. Specifically, they want to determine whether a person is alive or dead 10 years after a coronary incident and whether that is reflected in a significant difference in the patients’ cholesterol levels (chol58) taken when the event occurred. Use chol58 as a dependent variable and VITAL10 as your independent variable. Complete the following:

• Analyze these conditions to determine whether there is a significant difference between the cholesterol levels (vital10) of those who are alive 10 years later compared to those who died within 10 years.
• Include the SPSS output, which validates your conclusion.
• Write a brief paragraph describing your conclusions.

Refer to Unit 6 in the Green & Salkind text for specific information about SPSS tests and APA results interpretation and writing. Pay attention to the Levene’s test throughout for determining whether the assumption of equal variance was met when you make your final decisions about the analysis.

What conclusion did you reach? Write these conclusions in formal APA results format. Include your SPSS output to support that conclusion.

Part 3

Occasionally, you have 1 independent variable that has 3 or more levels or groups. For a parametric data set, an analysis of variance (ANOVA) is the proper calculation. Use an ANOVA to address the following scenario:

A financial planner is interested in understanding the relationship between the dependent variable of the income level of respondents (rincdol) and the independent variable of their education level (ndegree) from the gss.sav data file. Use SPSS to complete the following:

• Run an ANOVA to determine the overall conclusion.
• Use the Bonferroni correction as a post-hoc analysis to determine the relationship of specific levels of degree level to income.
• Explain the overall conclusions based on the analysis, and describe the relationship(s) between the levels of the degree earned and income.
• Write your conclusion of the findings based upon the output using proper APA formatting.

Submit both the SPSS output file and your Word summary. (Refer to the Green & Salkind section about a one-way ANOVA for information on APA results interpretation and writing.)
