For each of the problem given below, state the null and alternative hypotheses. Determine
the parameter to be tested and the level of significance. Write your answers in the table
below each assumption.
1. The breaking strengths of cables produced by a manufacturer have mean 1800 lbs.
and standard deviation 100 lbs. By a new technique in the manufacturing process, it is
claimed that the breaking strength can be increased. To test this claim, a sample of 50
cables is tested, and it is found that the mean breaking strength is 1850 lb. The claim is
supported using 0.01 level of significance.
