A sports equipment manufacturer has developed a new reasonably pricedgolf 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 theball travels. To compare distances, Sarah, a company researcher, conductsan experiment where 20 current balls and 20 new balls are subjected todistance tests, using a mechanical hitting device for consistency.The results of the tests, with distances given to the nearest metre, are givenin Table 1.Table 1 Distances travelled by golf ballsCurrent golf ballNew golf ball299292292291293285295288283273280305280286311308292291283296292294309281311286302302294296297303287298282293300290297284 (a) Sarah considers displaying the data as a pair of dotplots.

KidsFeet Parallel Scatterplots by Sex The KidsFeet dataframe contains data collected on 39 fourth grade students in Ann Arbor, MI, in October 1997. Two of the measurements taken on the children was the length, (length), and width, (width), of their longest foot. Based on the scatterplot shown below, there appears to be a positive linear association between the length and width of a fourth grader's biggest foot that holds even when the child's sex is accounted for. One of the following lines of code created everything in the graph below, except for the title and the axis labels. Which one was it?? ( ) xyplot(length~width, groups=sex, data=KidsFeet) ( ) xyplot(width~length,groups=sex,data=KidsFeet) ( ) xyplot(width~length|sex,data=KidsFeet) ( ) xyplot(width~length,groups=sex,data=KidsFeet, auto.key=TRUE) ( ) xyplot(length~width|sex, data=KidsFeet) ( ) xyplot(length~width, data=KidsFeet) ( ) xyplot(length~width, groups=sex, data=KidsFeet, auto.key=TRUE) ( )…
