A researcher would like to know whether there is a consistent, predictable relationship between ACT scores and GPA for high school students. A sample of 100 students is obtained from students who took the ACT in their Junior year. Based on the test results and gpa scores, students are classified as high or low for ACT and for GPA. The results are summarized in the following frequency distribution: ACT Score High Low High GPA 39 21 Low GPA 15 25 Based on the data, is there a significant relationship between ACT scores and GPA (α = .05). Compute the appropriate measure of association.

A real estate developer wishes to study the relationship between the size of home a client will purchase (in square feet) and other variables. Possible independent variables include the family income, family size, whether there is a senior adult parent living with the family (1 for yes, 0 for no), and the total years of education beyond high school for the husband and wife. The sample information is reported below. Family Square Feet Income (000s) Family Size Senior Parent Education 1 2,300 60.8 2 0 4 2 2,300 68.4 3 1 6 3 3,400 104.5 3 0 7 4 3,360 89.3 4 1 0 5 3,000 72.2 4 0 2 6 2,900 113 2 1 10 7 4,100 125.4 5 0 6 8 2,250 83.6 3 0 8 9 4,200 133 5 0 2 10 2,800 95 3 0 6 Click here for the Excel Data File Develop an appropriate multiple regression equation using stepwise regression.

A J.D. Power and Associates vehicle quality survey asked new owners a variety of questions about their recently purchased automobile One question asked for the owner's rating of the vehicle using categorical responses of average, outstanding, and exceptional. Anothe question asked for the owner's education level with the categorical responses some high school, high school graduate, some college, and college graduate. Assume the sample data below are for 500 owners who had recently purchased an automobile. Education Quality Rating Average Outstanding Exceptional Some HS HS Grad Some College College Grad 35 30 25 65 50 50 50 95 15 20 25 40 a. Use a 0.05 level of significance and a test of independence to determine if a new owner's vehicle quality rating is independent of th owner's education. Compute the value of the test statistic (to 2 decimals). 6.57 Use Table 3 of Appendix B to find the p-value. The p-value is greater than 0.10 What is your conclusion? Cannot conclude that the…

Health insurance benefits vary by the size of the company. The sample data below show the number of companies providing health insurance for small, medium, and large companies. For purposes of this study, small companies are companies that have fewer than 100 employees. Medium-sized companies have 100 to 999 employees, and large companies have 1,000 or more employees. The questionnaire sent to 225 employees asked whether or not the employee had health insurance and then asked the employee to indicate the size of the company. Health Insurance Size of the Company Small Medium Large Yes 33 62 85 No 17 13 15 (a) Conduct a test of independence to determine whether health insurance coverage is independent of the size of the company. State the null and alternative hypotheses.
