the median is 90 Q1 = 85 (84+86=170/2) Q3 = 93 (92+94=186/2) IQR = 8 (93-85) range = 20
(100-80) Two students compared the scores on their math tests. Their results on 9 tests are shown
in the box plots below. Compare the box plots. Which statements are true? Check all that apply.
*Ben has the smaller range of test scores. *The lower quartile and upper quartile of Nadia's data
are both higher than the lower quartile and upper quartile of Ben's data. *The median of Nadia's
data is equal to the median of Ben's data. *Nadia had the highest score on a test. *Ben's lowest
score was equal to Nadia's lowest score. correct answer* The median of Nadia's data is equal to
the median of Ben's data. * Nadia had the highest score on a test. A football coach compared the
yards per game of two of his running backs over the course of 10 games. Based on the data
represented in the box plots, which football player had greater success during the 10 games?
*Nasir was more successful because he had the greatest number of yards in one game. *Aaron was
more successful because he had the greater total spread. *Nasir was more successful because he
had the greater measure of center. *Aaron was more successful because he had an outlier. correct

player recorded her points for 11 consecutive games. Her points are listed below. 13, 20, 15, 22, 24,
21, 18, 20, 25, 17, 27 How many points would she need to score in her 12th game in order to
decrease the interquartile range by 1 point? correct answer*23 Which statement is true about the
box plots? (about Marc and Sue's classes wrong test answers) correct answer* The ranges for the
box plots are the same, but their interquartile ranges are different. The data set below has a lower
quartile of 13 and an upper quartile of 37. 1, 12, 13, 15, 18, 20, 35, 37, 40, 78 Which statement is
true about any outliers of the data set? *The data set does not have any outliers. *The lowest value,
1, is the only outlier. *The greatest value, 78, is the only outlier. *Both 1 and 78 are outliers. correct
answer* The greatest value, 78, is the only outlier. The box plot represents the number of minutes
