2. The formula for a regression equation is Y = 2X + 9.

a. What would be the predicted score for a person scoring 6 on X?

b. If someones predicted score was 14, what was this persons score on X?

6.For the(X,Y)datapointsbelow, compute:

Data Points: (4,6), (3,7), (5,12), (11,17), (10,9), (14,21)

a. The correlation (r)and determine if it is significantly different from a hypothesized slope of 0 (nullhypothesis).

HINT: Use the significance test for correlation on Page-482 and assume a 95% confidence.

b. The slopeand interceptof thelinear regression line
