After
Before
40 45 50 55 60 65 70 75
80 35
90 95 100 105 110
Which statement is true about the variability of the distributions?
The interquartile range of the typing speeds after the course is greater than the interquartile range of the speeds before
the course
The interquartile ranges of the two distributions are the same.
