(A) TRUE (B) FALSE Decide in each case whether or not you should reject the null hypothesis H_0: mu lessthanorequalto 2 in favor of the alternative hypothesis H_A: mu > 2 at significance level alpha = 0.05. T = - 2.5 and n = 42. (A) Reject (B) Fail to reject The p-value of the test is 0.0001. (A) Reject (B) Fail to reject T = 0.0001 and n = 42. (A) Reject (B) Fail to reject
