Q.4) Two variables x and y are believed to have a straight-line relationship. We
would like to predict y from x. Minitab tells us this about x and y:
Descriptive Statistics: x, y
Variable NO. Mean StDev Minimum Maximum Median
4.32
7.00
1.00
13 00
7.00
y
13.43
21.00
13.00
4.43
8.00
Pearson correlation of x and y 0.941
Use this information for this question and the two following What is the intercept of
the regression line for predicting y from x?
