Business Statistics Week 2

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 homeplate 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.
 

Seats		CF
38805		420
41118		400
56000		400
45030		400
34077		400
40793		400
56144		408
50516		400
40615		400
48190		406
36331		434
43405		405
48911		400
50449		415
50091		400
43772		404
49033		407
47447		405
40120		422
41503		404
40950		435
38496		400
41900		400
42271		404
43647		401
42600		396
46200		400
41222		403
52355		408
45000		408

 

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.
