I know I can only ask one question at a time, but Part B goes with it and it impossible to ask them separately. Please help. Your help will be very much appreciated. Thank you!

a) The table below displays results from a random sample of German Shepherd puppies at two different breeders that reported the average weight (in pounds) of the past month's litter. Is there a statistically significant difference in the weight of German Shepherd puppies at the different breeders? Use the five-step model and an alpha level of 0.05. Make sure that you interpret the results in terms of the original research question. (7.5 points) Breeder Breeder A B X1 = 5.7 X2 = 6.6 S1 = 1.6 S2= 4.1 n1 = 280 n2= 345 b) Suppose only 46 German Shepherd puppies were randomly selected from breeder A and 52 were randomly selected from breeder B. Would you reach the same conclusion as you did in Part A of this question? Why or why not? Use the five-step model and an alpha level of 0.05. (7.5 points)
