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?

Question 2

Power can be defined as
 
  a. One plus beta
  b. Two plus beta
  c. One minus beta
  d. One minus alpha
