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. Click here to view the sample data. Click here to view Student's t-distribution table. The samples are independent. O D. The population is given to be normally distributed. YE. The sample sizes are large (both greater than or equal to 30). c) Does the evidence suggest that community college transfer students take longer to attain a bachelor's degree? Use an a = 0.01 level of significance. Perform a hypothesis test. Determine the null and alternative hypotheses. O A. Ho: Hcommunity college Pno transfer O B. Ho: Hcommunity college > Hno transfer: H1: Hcommunity college Hno transfer C C. Ho: Hcommunity college =Pno transfer: H: Pcommunity college Pno transfer O D. Ho: Hcommunity college = Pno transfer: H;Hcommunity college Pno transfer Determine the test statistic. t= (Round to two decimal places as needed.)

Yc. The samples are independent.
O D. The population is given to be normally distributed.
E. The sample sizes are large (both greater than or equal to 30).
c) Does the evidence suggest that community college transfer students take longer to attain a bachelor's degree? Use an a = 0.01 level of significance. Perform a
hypothesis test. Determine the null and alternative hypotheses.
O A. Ho: Hcommunity college <Hno transfer: H1: Hcommunity college > Hno transfer
O B. Ho: Hcommunity college >Hno transfer: H1: Hcommunity college <Hno transfer
O C. Ho: Hcommunity college = Hno transfer: H1: Hcommunity college >Hno transfer
O D. Ho: Hcommunity college Pno transfer: HHcommunity college <Hno transfer
Determine the test statistic.
