The auditor conducts a hypothesis test for the mean and ends up with a p-value of 0.0046. Since the p-value of 0.0046 is less than the significance level of 0.01, the auditor rejects the null hypothesis. He concludes that there is sufficient evidence to ...

In practice, we don’t usually care about the p-value for the intercept term. Even if the p-value isn’t less than some significance level (e.g. 0.05), we would still keep the intercept term in the model.
WebJun 16, 2024 · two-tailed p-value: 0.0045. 4. Reject or fail to reject the null hypothesis. Since the p-value (0.0045) is less than the significance level (0.01) we reject the null hypothesis. We have sufficient evidence to say that the mean vertical jump before and after participating in the training program is not equal.
