Given the following hypotheses:

H0: μ = 530

H1: μ ≠ 530

A random sample of 9 observations is selected from a normal population. The sample mean was 535 and the sample standard deviation 8. Using the 0.05 significance level:

1. State the decision rule. (Negative amount should be indicated by a minus sign. Round your answers to 3 decimal places.)

reject H0 when the test statistic is (inside/outside) the interval (_____,_____)

2. Compute the value of the test statistic. (Round your answer to 3 decimal places.)

3. What is your decision regarding the null hypothesis?

Do not reject OR Reject
