Use the table of values to determine the line of regression. Determine if the regression line would be a good predictor of other data points.

x 7.2 7.4 9.8 9.4 8.8 8.4
y 116 154 245 202 200 191

A. ŷ = 40.2 - 157x; yes, because the r-value is high.

B. ŷ = -157 + 40.2x; yes, because the r-value is high.

C. ŷ = -157 +40.2x; no, because the r-value is low.

D. ŷ = 40.2 - 157x; no, because the r-value is low.

We wish to determine the impact of Specification Buying, X11, on Satisfaction Level, X10. To do so we will split the Hatco data file into two separate data sets based on the Specification Buying, X11. This variable has two categories: 1=employs total value analysis approach, evaluating each purchase separately; 0 = use of specification buying. Sort the entire Hatco data set based on Specification Buying. This will create two separate groups of records. Those records with X11 = 0 and...
