The following data represent the speed at which a ball was hit (in miles per hour) and the distance it traveled (in feet) for a random sample of home runs in a Major League baseball game in 2018. Complete parts (a) through (f). Click here to view.the data Click here to view the critical values of the correlation.coefficient. (a) Find the least-squares regression line treating speed at which the ball was hit as the explanatory variable and distance the ball traveled as the response variable. (Round to three decimal places as needed.) (b) Interpret the slope and y-intercept, if appropriate. Begin by interpreting the slope. - X Data table O A. The slope of this least-squares regression line says that the distance the ball travels increases by the slope with every 1 mile per hour increase in the speed that the ball was hit. O B. The slope of this least-squares regression line shows the increase in the speed that the ball was hit with every 1 foot increase in the distance that the ball was hit. Speed (mph) Distance (feet) o O C. The slope of this least-squares regression line shows the distance that the ball would travel when the speed that the ball is hit is zero. 110.4 427 O D. Interpreting the slope is not appropriate. 105.5 414 101.4 399 Now interpret the y-intercept 100.7 396 103.5 422 O A. The y-intercept of this least-squares regression line shows the speed that the ball is hit at when the distance that the ball travels is zero. O B. The y-intercept of this least-squares regression line shows the distance that the ball would travel when the speed that the ball is hit is zero. O C. The y-intercept of this least-squares regression line shows the increase in the speed that the ball was hit with every 1 foot increase in the distance that the ball was hit O D. Interpreting the y-Intercept is not appropriate 101.7 411 103.6 402 99.3 394 100.3 392 102.1 392 (c) Predict the mean distance of al home runs hit at 107 mph, 105.4 418 101.2 392 The mean distance of all home runs hit at 107 mph is feet (Round to one decimal place as needed)
