Can you explain what this question is asking specifically and how to get to the answer?

Given :

95 subjects were tested to see if heart rate exceeds during laughter.

Known :

Null hypothesis : = 71bpm

Alternative hypothesis : >71bpm

X Bar : 72.3

Standard Deviation : 8.2

Alpha : 0.05

P Value : 0.061

At the alpha level of 0.05 is there sufficient evidence to suggest that the mean resting heart rate exceeds 71bpm?

    The decision rule is

    REJECT the null hypothesis, if the p-value is < the alpha value

    FAIL TO REJECT the null hypothesis, if p-value is >/= the alpha value

    Since p-value (0.061) > the alpha value (0.05), it can be said that the test/sample data failed to reject the null hypothesis

    It can be inferred that there is NO sufficient evidence to suggest that the mean resting heart rate exceeds 71 bpm
