b. What is the response variable?
The values of miss america and gpa
c. What is the explanatory variable?
Miss America
d. Does the yintercept have any logical interpretation?
No
e. Interpret the slope in terms of how GPA changes as Miss America increases.
unknown

ANYONE HAVE ANY HELP FOR ME ON THIS???

Regression equation is predicted y = a + bx
...where a represents the yintercept and b the slope.

Explanatory or Predictor Variable = x (Miss America)
Response or Outcome Variable = y
(GPA)

YIntercept = 3.32
YIntercept Interpretation: If x = 0, we would expect GPA to equal 3.32.

Slope Interpretation: For every increase in value by 1, you can expect an additional decrease of 0.0890 in the GPA.

Hope this helps.
