Question #42086

A special cable has a breaking strength of 800 lbs. The standard deviation

of the population is 14 lbs. A researcher selects a sample of 36 cables and

finds that the average breaking strength is 794 lbs. Can one reject the

claim that the breaking strength is 800 lbs? Find the P-value. Should

H0

be rejected at = 0.01? Assume that the variable is normally distributed.
