Do the following with the SLC Softball data that you receive.
1) (2 pts) State the source of the data and the date or dates on which it was accessed.
2) (2 pts) Include a table showing your data at the end of this project.
3) (6 pts) Create a table having the following format and fill in the table using statistics for the two quantitative variables from the data you received. Replace “Variable 1” and “Variable 2” with the names of your two quantitative variables.

4) (4 pts) Find the 95% confidence intervals for the population means of each of your two quantitative variables.
5) (8 pts) Create a bar chart of the teams. Include a title with a note saying you created the graph, label both axes, and add horizontal grid lines.
6) (6 pts) Write a paragraph that answers each of the following questions about the bar chart you created for problem (5).
7) (8 pts) At 90% confidence, use the chisquare goodnessoffit test to see if the teams are equally likely. State the test statistic, the Pvalue and your conclusion in English.
8) (8 pts) Make sidebyside horizontal boxplots of your two quantitative variables. Include a title with a note saying you created the graph, identify each boxplot, label the horizontal axis including units if necessary, and add vertical grid lines.
9) (8 pts) Write a paragraph that answers each of the following questions about the horizontal boxplots you created for problem (8).
10) (8 pts) At 98% confidence, use the paired ttest to see if the means of your two quantitative variables are different. State the test statistic, the Pvalue and your conclusion in English.
