Need help with the following question:

We have a sample from a normal distribution. Sample size is 7. Sample

mean is 4.6, and sample standard deviation is 0.7. Test the null

hypothesis H0: u = 5 vs. the alternative hypothesis

Ha: u not equal to 5. You can use the percentiles from previous problems.

(a) Compute the test statistic

(b) Compute the rejection region at 0.05 significance level

(c) Compute the rejection region at 0.10 significance level

(d) At 0.05 significance level, what is your conclusion about

the test?
