Please provide explanation.

For each of the situations, set up the rejection region:

(a) H0 : µ1 = µ2 versus Ha : µ1 6= µ2 with n1 = 12, n2 = 15, and α = 0.05

(b) H0 : µ1 ≤ µ2 + 3 versus Ha : µ1 > µ2 + 3 with n1 = n2 = 25, and α = 0.01

(c) H0 : µ1 ≥ µ2 − 9 versus Ha : µ1 < µ2 − 9 with n1 = 13, n2 = 15, and α = 0.025

A craft brewer sells beer in 2 nearby towns. Some months, he sells more in Town 1 & other months hesells more in Town 2. However, he is pretty sure that he usually sells more in Town 1. So, he has set up the following hypothesis test. He has also looked up the sales figures from the last 30 months in both towns and calculated some sample statistics. Those are below too. Use this information to answer/do the following. H0...
