Question

Comment on one aspect of the comparison of data from the two
datasets that can be seen more easily on the histograms than on
the boxplots.

A sports equipment manufacturer has developed a new reasonably priced golf ball that it hopes will allow average golfers to hit the ball straighter. A concern is that this new technology might impact on the distance that the ball travels. To compare distances, Sarah, a company researcher, conducts an experiment where 20 current balls and 20 new balls are subjected to distance tests, using a mechanical hitting device for consistency. The results of the tests, with distances given to the nearest metre, are given in Table 1. Table 1 Distances travelled by golf balls Current golf ball New golf ball 292 299 291 292 293 285 295 288 280 283 305 273 280 286 291 311 283 308 296 292 292 294 309 281 311 286 302 302 294 296 297 303 287 298 282 293 300 290 297 284
