The pvalue for testing H0 Mu 100 against Ha Mu not equal to

The p-value for testing H0: Mu = 100 against Ha: Mu not equal to 100 is 0.001. This indicates that a. There is strong evidence that Mu = 100. b. There is strong evidence that Mu not equal to 100, since if Mu were equal to 100, it would be unusual to obtain data such as those observed. c. The probability that Mu = 100 is 0.00 1. d. The probability that Mu = 100 is the significance level, usually taken to be 0.05.

Solution

when p value is < 0.5, we reject the null hypothesis. hence the answer is b.
