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. The range of the speeds after the course is smaller than the range of the speeds before the course. The ranges of the two distributions are the same.

The value √10 and √15 are plotted on the number line

Use the frequency distribution, which shows the number of american voters (in millions) according to age, to find the probability that a voter chosen at random is in the 18 to 20 years old age range. ages frequency 18 to 20 5.9 21 to 24 7.7 25 to 34 20.4 35 to 44 25.1 45 to 64 54.4 65 and over 27.7 the probability that a voter chosen at random is in the 18 to 20 years old age range is nothing. (round to three decimal places as needed.)
