Question

You are reading an analysis of the correlation between diet soda consumption and weight gain. The authors state that the correlation coefficient between diet soda consumption and weight gain is 0.85 and the significance level (p-value) of the correlation coefficient is 0.75.

Which of the following statements is incorrect?

Group of answer choices

Given a significance level of 0.75, the authors appear to have sufficient empirical evidence to reject the null hypothesis of no correlation between consumption and weight gain.

There appears to be a strong, positive correlation between diet soda consumption and weight gain.

The authors cannot reject the null hypothesis of no correlation as the p-value does not reach normally accepted levels of significance..

If the significance level of the test was 0.05 (5%) instead of 0.25 (25%), the authors could reject the null hypothesis of no correlation.
