Answer: D
Explanation:
Answer: D. Because the P-value is greater than 0.05, the null hypothesis should not be rejected.
The P-value is a measure of the probability of obtaining a sample mean at least as extreme as the one that was observed, if the null hypothesis is true. A P-value of greater than 0.05 means that there is not enough evidence to reject the null hypothesis. Therefore, in this case, the data provides insufficient evidence to conclude that the true mean number of junk emails received this day by employees of this company differs from 100.
