Zappos Is an Online Retailer Based in Nevada and Employs

Zappos is an online retailer based in Nevada and employs 1,300 employees. One of their competitors, Amazon.com, would like to test the hypothesis that the average age of a Zappos employee is less than 36 years old. A random sample of 22 Zappos employees was found to have an average age of 33.9 years. The standard deviation for this sample was 4.1 years. Amazon would like to set α = 0.025. The conclusion for this hypothesis test would be that because the test statistic is ----

A) less than the critical value, we cannot conclude that the average age of Zappos employees is less than 36 years old.
B) more than the critical value, we cannot conclude that the average age of Zappos employees is less than 36 years old.
C) less than the critical value, we can conclude that the average age of Zappos employees is less than 36 years old.
D) more than the critical value, we can conclude that the average age of Zappos employees is less than 36 years old.
