MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER The number of passes completed and the total number of passing yards were recorded for the Los Angeles Chargers quarterback, Philip Rivers, for each of the 16 regular season games that he played in the fall of 2017.+ Week Completions (x) Yardage (y) | Week Completions (x) Yardage (y) 28 387 10 17 212 22 290 15 183 20 227 12 25 268 18 319 13 21 258 31 344 14 22 347 27 434 15 20 237 20 251 16 31 331 21 235 22 192 LO USE SALT (a) Draw a scatterplot to describe the relationship between number of completions and total passing yards for Philip Rivers. 35 100 30 30 $50 350 25 25 300 300 250 20 200 15 15 O 15 20 35 200 250 300 350 400 20 25 30 35 200 250 300 350 400 (b) Describe the plot in part (a). Do you see any outliers? There are no outliers to the linear trend, but there is an unusually high number of completions in Week 5. There are no outliers to the linear trend, but there is an unusually low number of completions in Week 11. The observation for Week 5 is an outlier. The observation for Week 11 is an outlier The observations for Weeks 5 and 11 are outliers. (c) Calculate the correlation coefficient, r, between the number of completions and total passing yards. (Round your answer to four decimal places.) = 0.696 x (d) What is the regression line for predicting total number of passing yards y based on the total number of completions x? (Round your numeric values to three decimal places.) y = 39.044 + 10.779x (e) If Philip Rivers had 28 pass completions in his next game, what would you predict his total number of passing yards to be? (Round your answer to three decimal places.) 340.856 x yd
