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 rst attended community college took longer to attain a bachelors 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 park a) through e) below. a Click the icon to view the sample data. a) What is the response variable in this study? What is the explanatory variable? 0 A. The response variable is the time to graduate, The explanatory variable is the use of community college or not. Q B. The response variable is the use of community college or not. The explanatory variable is the time to graduate. O c. The response variable is the time to graduate, The explanatory variable is the number of students. 0 D. The response variable is the number of students. The explanatory variable is the time to graduate. b) Explain why this study can be analyzed using inference of two sample means. Determine what qualications are met to perform the hypothesis test about the ditference between two means. Select all that apply. A. The sample sizes are not more than 5% of the population, The samples can be reasonably assumed to be random. The samples are independent. The population is given to be normally distributed. n .mppw 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 = 0.10 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 = Hno transfer, H1: Hcommunity college
