|t-test of the Football Data
In this activity, you will be performing a t-test on
the football data set to determine
whether there is a significant difference between the kicking distances of a football
filled with helium and one filled with regular air. The data was collected by a researcher
at Ohio State University. Each football was kicked
39 times on a windless day, and the two footballs were alternated with each kick. The
experimenter recorded the distance in yards traveled by each ball.
As a reminder, go to the Data ribbon and the Analysis Group and select Data Analysis. Scroll in the box until you find and select the t-test, 2-sample, assuming equal variances. Then,

Your answer to question 1, should be in cell A16. Ensure that each answer is a complete sentence. For example, for question one, the answer would be in this format:
