An experiment to determine how the weight of bat

Reference no: EM13339170

A baseball player would like to conduct an experiment to determine how the weight of his bat, the speed of a pitch and the type of pitch affect the distance he can hit the ball in the air. The player will examine two different bat weights (32 ounces or 35 ounces), three pitch speeds (70, 80 or 90 miles per hour) and two types of pitch (fastball or curveball). Pitches will be thrown by a pitching machine to guarantee consistency. The baseball player will hit 15 balls using each of the factor level combinations, and the distance (in feet) that each ball travels before hitting the ground will be recorded.

1. Identify the following in this experiment:

(a) experimental units

(b) response variable

(c) factors

(d) factor levels

(e) treatments

(f) How should randomization be used in this experiment? Explain why this randomization is important.

(g) Suppose that one of the treatments results in the baseball player consistently hitting the ball farther than for the other treatments. Can we say that the treatment is the cause? Explain.
