(Negative amount should be indicated by a minus sign. Round your answer to 3 decimal places.) Reject H0: u 2 11 and fail to reject H1: u < 11 when the test statistic is b. Compute the value of the test statistic. (Negative amount should be indicated by a minus sign. Round your answer to 2 decimal places.) Value of the test statistic
