Question

Assume that a simple random sample has been selected from a normally distributed population and test the given claim. Identify the null and alternative hypotheses, test statistic, P-value, critical value(s), and state the final conclusion that addresses the original claim. A simple random sample of 25 filtered 100 mm cigarettes is obtained, and the tar content of each cigarette is measured. The sample has a mean of 19.2 mg and a standard deviation of 3.56 mg. Use a 0.05 significance level to test the claim that the mean tar content of filtered 100 mm cigarettes is less than 21.1 mg, which is the mean for unfiltered king size cigarettes. What do the results suggest, if anything, about the effectiveness of the filters?

What are the hypotheses?

Identify the test statistic.

Identify the critical value(s).

State the final conclusion that addresses the original claim.

What do the results suggest, if anything, about the effectiveness of the filters?

A simple random sample of 25 filtered 100 mm cigarettes is
obtained and the tar content of each cigarette is measured. The
sample has a mean of 15 mg and a standard deviation of 4 mg. Use a
0.05 significance level to test the claim that the mean tar content
of filtered 100 mm cigarettes is less than 20 mg, which is the mean
for unfiltered king size cigarettes. What do the results suggest
about the effectiveness of the filters?...
