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:
- State the decision rule: (round 3 decimals)Reject H0 if t >
- Value of the test statistic (round 3 decimals)
