task 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

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.
