A simple random sample of 30 men from a normally distributed population results in a standard deviation of 9.3 beats per minute. The normal range of pulse rates of adults is typically given as 60 to 100 beats per minute. If the range rule of thumb is applied to that normalrange, the result is a standard deviation of 10 beats per minute. Use the sample results with a 0.10 significance level to test the claim that pulse rates of men have a standard deviation equal to 10 beats per minute. Complete parts(a) through(d) below.

a. Identify the null and alternative hypotheses.

b. Compute the test statistic.

c. Find theP-value.

d. State the conclusion.

Reject, Do not reject H0, because theP-value is less than or equal to, greater than the level of significance. There is sufficient, insufficient evidence to warrant rejection of the claim that the standard deviation ofmen's pulse rates is equal to 10 beats per minute.
