A corporate researcher runs Pearson r correlations among three variables, net income, gross income and amount spent on advertising. All correlations are significant.
Net Income and Gross Income = .60
Net Income and Advertising = .
53
Gross Income and Advertising = .35
Find the multiple R for predicting net income from both gross income and
advertising.
For questions 116 through 119, use the following:
A researcher collects the following measures:
Y mean = 50, with a standard deviation of 10
X1 mean = 100, with a standard deviation of 15
X2 mean = 200, with a standard deviation of 20
Significant correlations among the variables were found to be as follows:
y and 1 = .60
y and 2 = .75
1 and 2 = .20
What will be an ideal response?
