Question

In

quality–control

applications of hypothesis​ testing, the null and alternative hypotheses are frequently specified as

H0​:

The production process is performing satisfactorily and

Ha​:

The process is performing in an unsatisfactory manner.​ Accordingly,

α

is sometimes referred to as the​ producer's risk, while

β

is called the​ consumer's risk. An injection molder produces plastic golf tees with a mean weight of

0.252

ounce. To investigate whether the injection molder is operating​ satisfactorily,

40

tees were randomly sampled from the last​ hour's production. Their weights​ (in ounces) are listed in the accompanying table. Complete parts a through
