Question

My calculation for this was:

437.539-395.615 +/- 2.388 x 13.847

Upper bound = 41.924 + 33.07 = 74.994 which is correct

Lower bound = 41.924 - 33.07 = 8.854 which was incorrect for some reason.

Barry Bonds, Mark McGwire, and Sammy Sosa are 3 well-known (for a variety of reasons) home run-hitting former baseball players who hit most of their home runs during Major League Baseball's steroid era Do the home runs hit by Barry Bonds, Mark McGwire, and Sammy Sosa have the same mean distances? In the current data-rich environment, the mean distances B.4M, and , of all the home runs hit by, respectively, Bonds, McGwire, and Sosa are probably available somewhere, but assume this complete information is currently not available. All we have available for each player are the distances of 13 randomly selected home runs that the player hit The table below shows the 13 home run distances we have for each player. Bonds McGwire Sosa 410 430 410 390 429 420 510 400 400380 440390 461 350 360 364 480380 460 360420 510 430 458344 410 390 398 410 360 360 430 415 370 417 375 404 404 405 Let Ilg, M , and s be, respectively, the mean home run distance for Bonds, McGwire, and Sosa
