Given the following hypotheses:
H0 : μ ≤ 10
H1 : μ > 10
A random sample of 10 observations is selected from a normal population. The sample mean was 12 and the sample standard deviation 3. Using the .05 significance level:
a. State the decision rule. (Round your answer to 3 decimal places.)
Reject H0 if t >__________
b. Compute the value of the test statistic. (Round your answer to 3 decimal places.)
What is the Value of the test statistic:
