Research has shown that elementary school children who eat a hearty breakfast have better scores in cognitive tasks as compared with students who do not regularly have a hearty breakfast. The data below are similar to that obtained from a single classroom at a school.

Hearty breakfast- 10, 8, 7, 9, 13, 7, 6, 12

Light breakfast- 7, 4, 9, 3, 7, 6, 10, 2

Using a hypothesis test, are the test scores significantly lower for those with light breakfast than those with hearty breafast? Use a one-tailed test with alpha = 0.05. In your response, make sure to include: Null and alternative hypotheses, Pooled variance, Estimated error, The test statistic, and Your decision
