Given the following hypotheses:
H0: μ ≤ 13
H1: μ > 13
A random sample of 10 observations is selected from a normal population. The sample mean was 12 and the sample standard deviation 4.3. Using the 0.1 significance level:
State the decision rule. (Round your answer to 3 decimal places.)
Reject H0 if t >_____________
Compute the value of the test statistic. (Negative answers should be indicated by a minus sign. Round your answer to 3 decimal places.)
Value of the test statistic____________
