(c) Sarah can't remember which boxplot belongs to which set of balls. State
one way in which she could check by looking at the data for each set of
golf balls.
Transcribed Image Text:(c) Sarah can't remember which boxplot belongs to which set of balls. State one way in which she could check by looking at the data for each set of golf balls.
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.
