Question

Amy has conducted a one-tailed hypothesis test to see if the average starting salary for recent State University graduates is greater than $50,000. She calculated a test statistic of 2.06. Her sample consisted of 200 alumni. What is the p-value for Amy's result

Answer 1

Considering the situation described, the p-value for Amy's result is of 0.0203.

What are the hypotheses tested?

At the null hypotheses, it is tested if the mean is not greater than $50,000, that is:

$H_0: \mu \leq 50000$

At the alternative hypotheses, it is tested if the mean is greater, hence:

$H_1: \mu > \leq 50000$

We are testing if the mean is greater than a value, hence we have a right-tailed test. Using a right-tailed test with t = 2.06 and 200 - 1 = 199 df, the p-value is of 0.0203.
