Question 1

1. Baseball stadiums vary in age, style, size, and in many other ways. Fans might think of the size of the stadium in terms of the number of seats; while the player might measure the size of the stadium by the distance from the home plate to the centerfield fence. Note: CF = distance from home plate to centerfield fence.

Using the Excel add-in construct your scatter diagram with the data set provide below. Is there a relationship between these two measurements for the “size” of the 30 Major League Baseball stadiums?

a. Before you run your scatter diagram answer the following: What do you think you will find? Bigger fields have more seats? Smaller fields have more seats? No relationship exists between field size and number of seats? A strong relationship exists between field size and number of seats? Explain

c. Describe what the scatter diagram tells you, including a reaction to your answer in (a).

Question 2

Place a pair of dice in a cup, shake and dump them out. Observe the sum of dots. Record 2, 3, 4, …, 12. Repeat the process 25 times. Using your results, find the relative frequency for each of the values: 2, 3, 4, 5, …, 12.
