. (8 points) A little league baseball bat manufacturer can build aluminum bats using three different manufacturing processes.He wants to know whether the processes affect the power of the bat. He builds a bat-swinging machine that is designed to simulate a human batter, and he has the machine use each of the three bats to hit eight baseballs. He records the distance each ball travels (in feet) before it hits the ground, as shown in the table. Does manufacturing process affect bat power? Use alpha=.05.

- (2) What are the hypotheses in formal statistical notation?
- (1) Conduct this ANOVA using an online analysis tool. Report the results of the ANOVA (i.e., the f-test) using APA-style notation for reporting statistics.
- (2) What is your decision about the Null Hypothesis? Explain how you came to this decision.
- (3) If appropriate, conduct the post hoc tests and describe the results. That is, communicate the results in everyday language so that someone else can understand the findings, using the descriptive statistics for each groupto explain the pattern in the data. Feel free to draw a graph if that will help you describe the results.
