Answer #1

Using Excel, go to Data, select Data Analysis, choose t-Test: Two-Sample Assuming Unequal Variances.

Mid Final
Mean 81.825 78
Variance 69.994 101.641
Observations 40 40
Hypothesized Mean Difference 0
df 75
t Stat 1.847
P(T<=t) one-tail 0.0344
t Critical one-tail 1.665
P(T<=t) two-tail 0.069
t Critical two-tail 1.992

H0: μ1 = μ2

H1: μ1 > μ2

p-value = 0.034

Since p-value is less than 0.05, we reject the null hypothesis and conclude that μ1 > μ2.

So, students score lower on their final exxam than mid exxam.
