Test whether he given claim is supported or not supported using a 0.05 significance level. Assume that the sample has been randomly selected from a population with a normal distribution.

A manufacturer makes ball bearings that are supposed to have a mean weight of 30 grams. A retailer suspects that the mean weight is actually less than 30 grams. The mean weight for a random sample of 16 ball bearings is 28.5 grams with a standard deviation of 4 grams. Use a 0.05 significance level to test whether the claim that the mean is less than 30 grams is supported or not supported.
