Question

I understand how the level of signficance = 1.96 and I understand: Ho:μ=5 - Ha:μ<5

But I need help understanding how to calculate the test statistic. I know we have a sum of 93 with a sample size of 28 but how do you come to the conclusion for the test stastisic and how do you figure out whether you have enough proof to accept or reject the claim? Thank you.

A local school district claims that the number of school days missed by its teachers
due to illness is below the national average of µ = 5. A random sample of 28
teachers provided the data below. At a = 0.05, test the district's claim using P-
values.

Definition Definition Number of subjects or observations included in a study. A large sample size typically provides more reliable results and better representation of the population. As sample size and width of confidence interval are inversely related, if the sample size is increased, the width of the confidence interval decreases.
