Using the Major League Baseball Data Set available through the "Data Sets" link in the Materials section, answer the research problem 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 problem. 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, find out the test statistic, and draw conclusion.

c. Describe the results of your test, and describe how the findings from this hypothesis testing can be used to answer the research problem 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.
