A researcher has designed a study in order to examine whether keeping a written calendar improves academic performance among male and female college students. She plans to randomly assign 30 first-year students to the calendar condition. Fifteen will be male and fifteen will be female. These students will submit weekly calendars to their teacher in advance of every week for a period of 10 weeks. The control group will include 30 randomly assigned students, half male and half female. These students will not be required to complete or submit a calendar to their instructor. The grade point average of students at the end of the semester will be examined across the groups. A. What factor(s) are being examined? B. How many levels does each factor(s) have? C. State the null and alternate hypotheses that may be examined in this experiment. D. Compute the F-ratios and explain what you will conclude on the basis of the hypothesis test using an alpha level of .05 Male Female n= 15 n= 15 M= 2.9 Calendar N= 60 M= 3.2 G= 79 T= 15 T= 30 Σχ470 SS = 22 SS = 20 Control n= 15 М-24 n= 15 M= 2.6 T= 14 T= 20 SS = 8 SS = 20

3. A study was conducted to investigate the use of community-based treatment programs among Medicaid beneficiaries suffering from severe mental illness. The study involved assigning a sample of 311 patients to a prepaid medical plan and a sample of 310 patients to the traditional Medicaid program. After a specified period of time, the number of persons in each group who had visited a community crisis center in the previous three months was determined. Among the subjects assigned to the prepaid plan, 13 had visited a crisis center; among those receiving traditional Medicaid, 22 had visited a crisis center. a. Using Stata, test the null hypothesis that the proportions are identical in the two populations, at the 0.10 significance level. b. From the Stata output, what are your estimates of the two proportions? c. Using the information from the Stata output, calculate the 95% confidence interval for the true difference between the proportions. d. Use Stata to determine how much power you…
The University is considering changing the email system that they currently use. Since there are substantial learning costs associated with any new software, the University only wants to change to the new system if it is very confident that there is at least a 20% difference in the proportion of faculty and staff who say they like the new system. In a sample of 120 users of the current system, the University finds that 65 say they like the current system. In another sample of 90 experimental users of the “new” system, the University finds that 70 of them like the new system. When testing the hypothesis (using a 5% level of significance) that there is at least a 20% difference in the proportion of users who like the two systems, the p-value is .2943; what is your conclusion concerning the null hypothesis? Reject the null hypothesis Fail to reject the null hypothesis
