Thompson and Thompson is a steel bolt manufacturing company. Their
current steel bolts has a mean diameter of 140 mm and a variance of
36. If a random sample of 50 steel bolt is selected what is the
probability that the sample mean would be greater than 142.5 mm
round your answer to four decimal places

Suppose a batch of steel rods produced at a steel plant have a
mean length of 176 millimeters, and a variance of 100 . If 446 rods
are sampled at random from the batch, what is the probability that
the mean length of the sample rods would be less than 175.35
millimeters? Round your answer to four decimal places.

Suppose a batch of steel rods produced at a steel plant have a
mean length of 170 millimeters, and a standard deviation of 10
millimeters. If 299 rods are sampled at random from the batch, what
is the probability that the mean length of the sample rods would
differ from the population mean by greater than 0.7 millimeters?
Round your answer to four decimal places.
