Discuss the below:
Q1: How do you decide your null and alternative hypotheses?
Q2: How do you as a researcher decide the confidence level? What factors do you consider to make that decision?
Q3: How do you decide on the type of test? For example, should you use z-test, t-test, or non-parametric test that we will study later on [such as x^2 test, F-test]?
