Question

A survey was conducted to compare the proportion of senior and junior engineering students who favor to take a statistics course in the morning. It was found that among 170 senior students interviewed, 60 favored to take the course in the morning while out of 150 junior students 40 favored to take the course in the morning. a) Test at 5% significant level if the proportion of more than 25% of the junior students favored to take the course in the morning. b) Find a 95% confidence interval for the proportion of junior students who favored to take the course in the morning. c) Check all the assumptions needed to run the test in part (a). d) At the 5% significance level, are the true proportions among seniors and juniors in the college who favor to take course in the morning significantly different? e) Construct a 95% two sided confidence interval for the difference of the two proportions. f) Check all the assumptions needed to run the test in part (c)?
