The insurer wants to perform a hypothesis test to determine whether their suspicion is correct.The hypothesis tests are as follows: Null hypothesis: mean fee = $1200Alternative hypothesis: mean fee > $1200
A. Rejecting the null hypothesis means there is evidence that the mean fee is not equal to $1200. Failing to reject the null hypothesis means there is insufficient evidence to conclude that the mean fee is greater than $1200. B. Rejecting the null hypothesis means there is evidence that the mean fee is greater than $1200. Failing to reject the null hypothesis means there is insufficient evidence to conclude that the mean fee is greater than $1200. C. Rejecting the null hypothesis means there is evidence that the mean fee is greater than $1200. Accepting the null hypothesis means there is evidence to conclude that the mean fee is equal to $1200. D. Rejecting the null hypothesis means there is evidence that the mean fee is greater than $1200.
