Question: Suppose you are testing the following hypotheses:
Ho: = 3200
Ha: µ = 3200
Sample size is 9. The sample mean is 3260 and the sample standard deviation is 120. The significance level is .10. Assume that the values in the population are normally distributed.
- What are the critical t values, t cl and t cu for the test? State the decision rule.
- Compute the sample test statistic t.
- Should you reject the null hypothesis? Explain.
