Question

Number of Wins per Number of Losses

1. Slope   161.96

2. y-intercept -1.0004x

3. Coefficient of Determination   0.99937

4. Linear correlation coefficient 0.99968

Using r and At a .05 level of significance with n = 30 respond to questions 5 and 6 to

determine if there is a linear relationship between number of losses and number of wins.

5. From table A-5 The critical values r=

Complete the following statement by filling in the blanks and choosing the correct

answer from within parentheses:

6. Because the absolute value of r=

(exceeds/does not exceed)

the critical value of r=

there (is/is not) a linear correlation between number of losses and number of wins.

If there IS a linear relationship, complete the following statement regarding r2

7. About                    %   of the wins can be explained by the linear relationship

between number of losses and number of wins.

Explanation / Answer

5)
critical values for df =n-2 = 28 is r = 0.381

6)

r= 0.99968   exceeds

critical value of r = 0.381

hence
there is a linear correlation between number of losses and number of wins.

7)
this is given by R^2 =   0.99937
hence 99.937 % of the wins can be explained by the linear relationship

between number of losses and number of wins.
