Question: (10 points total)

Sometimes drugs are recalled because of failure to meet "content uniformity" requirements. Suppose that "content uniformity" is expressed in terms of variance. For example, suppose a "content uniformity" requirement specifies that the variance in the amount of Phenobarbital in tablets is supposed to be less than or equal to 0.015 grams ² .

The satisfaction of this requirement is being evaluated in a simple random sample of 30 tablets. For this sample, the sample standard deviation was found to be s=0.14 grams. Carry out the appropriate statistical hypothesis test to assess compliance with the content uniformity specification of variance less than or equal to 0.015 grams ² . In developing your answer, address the following:

8a (2 points) What is the null hypothesis?

8b ( 2 points) What is the alternative hypothesis?

8c (2 points) What is the appropriate test statistic and what is its value for these data?

8d ( 2 points) What is the p-value?

8e ( 2 points) In 1-2 sentences at most, what is your interpretation and conclusion?
