question 118

Short Answer

A faculty advisor was interested in determining whether there is a difference in the amount of time (in hours) spent studying on weeknights (Monday through Thursday) between male and female students. The advisor selected a sample of 12 female students and a second independent sample of 10 male students and asked each student to indicate the average amount of time they spend studying on a weeknight. The following summary statistics are obtained. The advisor assumed equal variances in the analysis. Is this a reasonable assumption? Perform the appropriate test of hypothesis to determine whether there is a significant difference in average time spent studying on weeknights between male and female students Test using = 0.05.
Approximate the p-value for the test in part (c). Using the p-value approach and = 0.10, what conclusion can be drawn about the difference in average time spent studying on weeknights between male and female students? Develop a 95% confidence interval for the average amount of time spent studying on week nights by females.
