To determine

To explain in this context what the “ $7\%$ ” represents.

Explanation of Solution

In this question, a researcher tests whether the mean cholesterol level among those who eat frozen pizza exceeds the value considered to indicate a health risk. And she gets a P-value of $0.07$ . Since the mean cholesterol of pizza eaters do not indicate a health risk, thenin this context the “ $7\%$ ” representsthat only $\text{7 out of a 100}$ samples would have mean levels higher than the observed sample.
