A traffic engineer puts a sensor along a small highway with a speed limit of 45 miles per hour to measure the speeds of vehicles. The engineer collects data during the same time period on a Saturday and
on a Monday. The box plots show the results.45
Saturday Morning
58
59 60
45 46 47 48 49 50 51 52 53 54 55 56 57
Speed (miles per hour)
Monday Morning
38
35 36 37
46
47
49

41 42
45
Speed (miles per hour)
Which statement regarding these data sets is correct?
Half the drivers on Monday drove faster than the posted speed limit.
O People drove at about the same speed on Saturday and on Monday,
The lowest speed measured on Saturday morning is equal to the highest speed measured on Monday morning,
The median speed for drivers on Saturday morning was 8 mph faster than the posted speed limit.
