Using the Major League Baseball Data Set available through the "Data Sets" link in the Materials section, answer the research question of whether or not the players are better as batters comparing to 20 years ago, i.e., the average BA (batting average, called Batting in the description of the data set) is higher than 0.252 (the average BA for the 1985 season) . Prepare a 750-1,050-word paper describing the process of using a statistical test to answer this research question. Be sure to include the following in your paper:
a. Formulate a set of verbal hypothesis statements (null and alternate hypothesis).
b. Describe and perform the five-step hypothesis test process: set up the hypothesis, select a level of significance, establish the decision rule, calculate the test statistic, and draw conclusion.
c. Describe the results of your test, and explain how the findings from this hypothesis testing can be used to answer the research question above.
Be sure to include, in an appendix, your raw data table and results of your computations of a z-test or t-test in your paper.
