15. As part of a science experiment, a student recorded 10 measurements of the temperature of a liquid. One ofthe measurements was an outlier when compared with the other 9 measurements. Which of the followingmust be true about the 9 measurements, excluding the outlier, when compared with the 10 measurements?(Note: An outlier is any number that is greater than the upper quartile or less than the lower quartile byat least 1.5 times the interquartile range.)(A) The median of the 9 measurements is less than the median of the 10 measurements.(B) The median of the 9 measurements is greater than the median of the 10 measurements.(C) The maximum of the 9 measurements is less than the maximum of the 10 measurements.(D) The maximum of the 9 measurements is greater than the maximum of the 10 measurements.(E) The standard deviation of the 9 measurements is less than the standard deviation of the 10 measurements.

Option (E) is the correct answer
