Question

The results of a state mathematics test for random samples of students taught by two different teachers at the same school are shown below. Can you conclude there is a difference in the mean mathematics test scores for the students of the two teachers?

Teacher 1	Teacher 2
xbar = 473	xbar = 459
S₁₌ 39.7	S₂ = 24.5
n₁ = 8	n₂ = 18

Identify the rejection region (critical region) and fail to reject region. Show this by drawing a curve and separate the rejection region from the fail to reject region using critical values.
