A manufacturing company is interested in predicting the number of defects that will be produced each hour on the assembly line. The managers believe that there is a relationship between the defect rate and the production rate per hour.
 
  The managers believe that they can use production rate to predict the number of defects. The following data were collected for 10 randomly selected hours.
 
  Defects Production Rate Per Hour
  20 400
  30 450
  10 350
  20 375
  30 400
  25 400
  30 450
  20 300
  10 300
  40 300
 
  Given these sample data, the simple linear regression model for predicting the number of defects is approximately = 5.67 + 0.048x.
   Indicate whether the statement is true or false

Question 2

Standard stepwise regression combines attributes of both forward selection and backward elimination.
 
  Indicate whether the statement is true or false
