A researcher with the Department of Education followed a cohort of students who graduated from high school in a certain year, monitoring the progress the students made toward completing a bachelor's degree. One aspect of his research was to determine whether students who first attended community college took longer to attain a bachelor's degree than those who immediately attended and remained at a 4-year institution. The data in the table attached below summarize the results of his study. Complete parts a) through e) below.

- 13.06 (Round to two decimal places as needed.) Determine the P-value. P-value = .000 (Round to three decimal places as needed.) Should the hypothesis be rejected? Reject the null hypothesis. The evidence does suggest that community college transfer students take longer to attain a bachelor's degree at the a= 0.05 level of significance. d) Construct a 99% confidence interval for Hcommunity college - Hno transfer to approximate the mean additional time it takes to complete a bachelor's degree if you begin in community college. The confidence interval is the range from to (Round to three decimal places as needed.)
