Question
A company that manufactures baseball bats believes that its new bat will allow players to hit the ball
30 feet farther than its current model. The owner hires a professional baseball player known for hitting home runs to hit ten balls
with each bat and he measures the distance each ball is hit to test the company's claim. The results of the batting experiment are
shown in the following table. Construct a
90 % confidence interval for the true difference between the mean distance hit with the new model and the mean distance hit
with the older model. Assume that the variances of the two populations are the same. Let Population 1 be the distances of balls hit
with the new model baseball bat and Population 2 be the distances of balls hit with the old model. Round the endpoints of the
interval to one decimal place, if necessary.
