Q7. Please show working in full and please hand write solutions clearly (please don't type)

Q7(10). A chicken farm is trying a new feed which was claimed to gain more weight. The farm has two chick coops. Coop A is given the traditional feed, coop B is given the new feed. Three months after, 6 chickens are randomly selected from each coop. The weights (kg) are as following: coop A: 2, 2.5, 3, 2.1, 2.2, 3.2. coop B: 3.5, 2.7, 2.8, 3.1, 2.9, 3. Let Ha, My be the population true average chicken weights in coop A and B, respectively. Assume the chicken weight in both coops are normal with equal variance. 1(6). Implement hypothesis test to determine if the coop B's average weight exceeds that of the coop A by more than 0.2kg. Significant level 0.05. Solve the question using reject region method. 2(4). Compute the 99% one-sided confidence interval with lower bound for the mean difference: /b - Ha
