Business Statistics Chapter 3&4

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 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? I would say that the majority of them are very close to the same size.

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.

I don’t think that there will be a relationship existing between field size and number of seats. I think that the number of seats just depends on average how many fans normally come to baseball games, and the popularity of the team.

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).

The diagram tells me that the number of seats and the size of stadium are very similar. It seems like the majority of them average about 400 CF and 40000 to 50000 seats. I think that after viewing the scatter chart that there is still no relationship existing between field size and...
