The weights of all the turkeys sold in Fairfax County in 2020 were recorded in the data set “Fairfax Turkey Weights” found in StatCrunch. The weights are presented in pounds. There are 235,428 turkeys in this population. -Calculate the probability that a randomly selected turkey weighs between 17 and 20 pounds using the Normal distribution and the rounded mean and standard deviation -Calculate the probability that, in a random sample of eight turkeys, the mean weight is between 17 and 20 pounds. First, draw a picture with the rounded mean and values labeled and the shaded area representing the desired probability. Then, complete this part by standardizing and using the Standard Normal
