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 homplate to the centerfield fence. Note: CF = distance from homeplate to centerfield fence.

Using the Excell 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.

b. Construct a scatter diagram and include it in your answer.

c. Describe what the scatter diagram tells you, including a reaction to your answer in (a).
Question 2

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.
