A fisherman claims that the mean breaking strength of his fishing line is 15 kg with a standard deviation of 500 g. To test the hypothesis that u = 15 kg against the alternative that p < 15 kg, a random sample of 50 of his fishing lines will be tested. With the critical region is defined to be x < 14.9, find the probability of committing a type Il error for u = 14.9.

The specifications for a certain kind of ribbon call for a mean breaking strength of 180 pounds. If five pieces of the ribbon (randomly selected from different rolls) have a mean breaking strength of 169.5 pounds with a standard deviation of 5.7 pounds, test the null hypothesis μ = 180 pounds against the alternative hypothesis μ < 180 pounds at the 0.01 level of significance. Assume that the population distribution is normal. a) Find the p value b) Test the...

The Breaking strengths of cables produced by a certain manufacturer have a mean, H, of 1750 pounds, and a standard deviation of 65 pounds, It is claimed that an improvement in the manufacturing process has increased the mean breaking strength. To evaluate this claim, 100 newly manufactured cables are randomly chosen and tested, and their mean breaking strength is found to be 1752 pounds. Can we support, at the 0.05 level of significance, the claim that the mean breaking strength...
