a) Perform a parametric test to answer this question at the 𝛼 =0.08 significance level. Assume all conditions are satisfied and donot check assumptions. State the test that you are using.
b) Construct the 92% parametric confidence interval.
c) Perform a non-parametric test to answer this question.
d) Construct the 92% confidence interval estimate using apercentile interval (non-parametric approach).
e) What are the conditions of the parametric approach you used?Which test and confidence interval would you report to David toanswer his question and why (i.e., should you have used theparametric or non-parametric approach)?
