Part 2 Q11 Help

Determine the test statistic. t = [ ] (Round to two decimal places as needed.) Determine the P-value. P-value = [ ] (Round to three decimal places as needed.) Should the hypothesis be rejected? [Dropdown Menu] the null hypothesis. The evidence [Dropdown Menu] suggest that community college transfer students take longer to attain a bachelor's degree at the α = 0.05 level of significance. d) Construct a 90% confidence interval for μ₁ (Community College) − μ₂ (No 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.) e) Do the results of parts c) and d) imply that community college causes you to take extra time to earn a bachelor's degree? [Radio Button] Yes [Radio Button] No

**Sample Data** This table presents data comparing the graduation timeline between students who transferred from community college and those who did not transfer. | | Community College Transfer | No Transfer | |-----------------------------------------|----------------------------|-------------| | **n** | 270 | 1152 | | **Sample mean time to graduate, in years** | 5.46 | 4.41 | | **Sample standard deviation time to graduate, in years** | 1.131 | 1.013 | - **n**: Sample size, representing the number of students in each category. - **Sample mean time to graduate, in years**: The average number of years taken to graduate. - **Sample standard deviation time to graduate, in years**: Measures the amount of variation or dispersion in the graduation time. **Summary:** Students who transferred from community colleges had a mean graduation time of 5.46 years with a standard deviation of 1.131 years. In contrast, students who did not transfer had a mean graduation time of 4.41 years with a standard deviation of 1.013 years.
