What are the null and alternative hypotheses?
a. upper h 0: muequals0 minutes upper h 1: muless than0 minutes
b. upper h 0: muless than0 minutes upper h 1: muequals0 minutes
c. upper h 0: muequals0 minutes upper h 1: mugreater than0 minutes
d. upper h 0: muequals0 minutes upper h 1: munot equals0 minutes your answer is correct. identify the test statistic. negative 7.50 (round to two decimal places as needed.)
1. identify the p-value. 0.000 (round to three decimal places as needed.)
2. state the final conclusion that addresses the original claim. fail to reject upper h 0.
a. there is not sufficient evidence to conclude that the original claim that the mean prediction error is equal to zero is correct.
b. there is no error in the mean prediction.
