Assume that the level of ∝=0.1 and use the given information to complete the problem.

The standard deviation of pulse rates of a certain group of adult males is more than 12 bpm. The hypothesis test results in aP-value of 0.2559.

Expert Solution

Step 1

Solution: The claim given in the question is that the standard deviation of pulse rates of a certain group of adult males is more than 12 bpm. Therefore, the null and alternative hypotheses are:

Step 2

Also, the p-value for the given hypothesis test is given as:

It is required here to draw the conclusion about the given claim in the question.

The decision rule in the hypothesis testing is:

Reject the null hypothesis if the p-value is less than the significance level.
