Sarah claims that her “miracle bait” is a more effective lure for panfish than the old- fashioned lure that Bill uses. Sarah and Bill went on 12 fishing expeditions in the same boat last summer and kept the following day-by-day record of the number of panfish they caught:

                              Days
               1   2  3  4  5  6  7  8  9 10 11 12

Sarah 8 27 7 9 18 15 13 19 3 12   18 12

Bill 13 20 2 9 19 12 10 23 0 11 15 10

Do these statistics support Sarah’s argument sufficiently to convince Bill to switch to her “miracle bait”, which is somewhat more expensive than the bait Billis currently using?
