Question

A sample has a mean of M = 42 and a standard deviation of s = 3.3, and produces a t statistic of t = 2.04. For a two-tailed hypothesis test that has a critical cutoff T of 1.96, do you reject the null or not?

a. none of the answers are correct

b. there is no way to tell if you can reject or not

c. cannot reject the null hypothesis

d. reject the null hypothesis

Answer 1

Since the test statistic value is greater than the upper critical value(2.04 > 1.96), so we should reject the null hypothesis.

Option - d) reject the null hypothesis
