A study of the amount of time it takes a mechanic to rebuild the transmission for a 2005 Chevrolet Cavalier shows that the mean is 8.4 hours and the standard deviation is 1.8 hours. If 40 mechanics are randomly selected, find the probability that their mean rebuild time exceeds 8.7 hours. a) (1pt) Define x-bar:  b) (1pt) Explain why  x-bar is normal c)  (3pts) Find the probability that their mean rebuild time exceeds 8.7 hours. Round the answer to 3 decimal places.

Solve the problem.The weights of the fish in a certain lake are normally distributed with a mean of 20 lb and a standard deviation of 9. If 9 fish are randomly selected, what is the probability that the mean weight will be between 17.6 and 23.6 lb? Make sure to first define x-bar and check its normality before calculating the probability (5pts)Define x bar:x bar is normal because: Prob=
