Observe randomly the weight of 100 chickens at farm A. The sample mean is 3.4 kg and sample standard deviation is 0.5. Observe r
andomly the weight of 200 chickens at farm B. The sample mean is 4.1 kg and sample standard deviation is 0.9. With the significance level of 2%, can we conclude that the true average weight of farm A is something other than farm B ?
