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.

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.
