Using the confidence interval, it is found that the correct conclusion regarding the hypotheses test is given by:
Reject H0. There is convincing evidence that this individual’s true mean heart rate while working out differs from 150.
<h3>What are the hypotheses tested?</h3>At the null hypotheses, it is tested if the mean is of 150, that is:
At the alternative hypotheses, it is tested if the mean is different of 150, hence:
.
The confidence interval is (158, 167). Since it does not contain 150, we reject the null hypotheses, hence the correct option is:
Reject H0. There is convincing evidence that this individual’s true mean heart rate while working out differs from 150.
