NAME: Problem 5. Ar thousands of rods). Assume that the mean length of the rods tn steel rods from a supplier (each lot consists of each lot is 3 meters and standard rods from that lot is at least 3.005 meters, otherwise the lot is returned to of the lots received by the manufacturer will be returned to the supplier? (4 a lot if the mean length of the randomly supplimple of 64rodste ality manthr the supplier. a) What percentage Points) If the distribution of the rod length in a lot were highly skewed, how would that affect your answer to part (a)? (1 Point) b) Answer.Explanation / Answer
Answer to the question is as follows:
a. P(X<=3.005) = P(Z<= 3.005-3 / (.03/sqrt(64)) = P(Z<=1.3333) = 0.9088
b. If it is highly skewed, lets say left skewed then this value is going to decrease
If it were right skewed, then this value is going to increase
