Question
Transcribed Image Text:To determine whether car ownership affects a student's academic achievement, two
random samples of 100 male students were each drawn from the student body. The
grade point average for the n₁ = 100 nonowners of cars had an average and variance
equal to ₁ 2.70 and s= .36, while ₂ 2.54 and s
.40 for the n₂
100 car
owners. Do the data present sufficient evidence to indicate a difference in the mean
achievements between car owners and nonowners of cars? Test using a = .05.
