A scientist collected the following weights (in grams) of laboratory animals:

Run @RISK’s distribution fitting procedure on the weights of the lab-oratory animals.
a. The normal distribution is often used with measurement variables such as height and weight. Compare the normal distribution to the empirical distribution by computing the following probability values for both distributions:
P (Weight ≤ 8 gms), P (Weight ≤ 9.5 gms), and P(Weight ≤ 11.5 gms) :
b. Do you think the normal distribution is a good choice for a theoretical distribution to fit these data? Why or why not?
