Suppose there is a claim that a certain population has a mean, u, that is different than 8. You want to test this claim. To do so, you collect a large random
sample from the population and perform a hypothesis test at the 0.05 level of significance. To start this test, you write the null hypothesis, Ho, and the
alternative hypothesis, H,, as follows.
Ho: u = 8
H: u = 8
Suppose you also know the following information.
The value of the test statistic based on the sample is 1.762 (rounded to 3 decimal places).
The p-value is 0.078 (rounded to 3 decimal places).
(a) Complete the steps below for this hypothesis test.
