Freshman tend to drop Statistics courses during the first week of the semester because the course seems too intimidating. The university administrative staff informs professors that the drop rate is 0.35 so that they can plan accordingly. A statistics professor randomly selects 60 students enrolled in various first year Statistics courses and observes that 28 of them actually dropped the courses. Is there enough evidence to conclude that the drop rate is not 0.35? What is the value of the test statistic? (Use α=0.05)  A. Test statistic: 1.658 Conclusion: Reject the null hypothesis  B. Test statistic: 1.658 Conclusion: Not enough evidence to reject the null hypothesis  C. Test statistic: 1.735 Conclusion: Not enough evidence to reject the null hypothesis  D. Test statistic: 1.735 Conclusion: Reject the null hypothesis

2-Proportion Test

In a 2-proportion test, two separate proportions are measured at the same time, and their similarity is evaluated. It is also known as a 2-proportion z-test, and a comparison of two different proportions is done in this method.
