Pass the ball:The NFL Scouting Combine is an event at which football scouts evaluate the abilities of some top college prospects. Following are heights in inches and weights in pounds for some of the quarterbacks at the 2013

Combine. Use the TI-84 Plus calculator to answer the following.

Name	Height	Weight
Zac Dysert	75	231
Marqueis Gray	75	240
Landry Jones	76	225
Collin Klein	77	226
E. J. Manuel	77	237
Ryan Nassib	74	227
Sean Renfree	75	219
Geno Smith	74	218

Send data to Excel you can do manually.

(a) Construct a scatterplot of the weight (y) versus the height (x).

Weight (pounds)

y 205 210 215 220 225 230 235 240 245 250 x 55 60 65 70 75 80 85 90 95 100 50

Height (inches)

(b) Compute the correlation coefficient between the height and weight of the quarterbacks. Round the answer to at least three decimal places.

(c) If a quarterback is below average in height, would you expect him to be above average or below average inweight? Explain.

I would expect the quarterback to be above or below ?average in weight since r is negative or postive?

Part 4 of 4

(d) Which of the following is the best interpretation of the correlation coefficient?

If a quarterback gains weight, he will grow taller. Given two quarterbacks, the taller one is likely to be heavier than the shorter one. Given two quarterbacks, the heavier one is likely to be shorter than the lighter one.
