Problem 1: What is the critical value? Describe the rejection region.

Answer and Explanation:

Now need to determine the critical value. Since this is a left tailed test, the formula to find the critical value usingexcel is =T.INV (α, df).

The significance level for this scenario is α =.05

Our degrees of freedom (df)= 363. The degrees of freedom were determined by taking the sample size of 364 and subtract 1.

The formula would be entered as = T.INV (0.05, 363) The answer I get is -1.649 My critical value = -1.649.

-2.548 > -1.649

Since our test statistic is greater than our critical value the rejection region is to the left of our critical value of -1.649 and includes our test statistic
