Question 1131147: A graphing calculator is recommended.
The data in the table below show the distance, in feet, a ball travels for various swing speeds, in miles per hour, of a bat.
Bat speed (mph) Distance (ft)
40 199
45 210
50 246
60 272
70 300
75 326
80 339
(a) Find the linear regression equation for these data. (Round all numerical values to three decimal places.)
y =
(b) Using the regression model, what is the expected distance a ball will travel when the bat speed is 58 miles per hour? Round to the nearest foot.__________ft
