For each of the following data sets, use your calculator to help find the interquartile range and the
population standard deviation. Show your calculation for the IQR. Round all non-integer values to the
nearest tenth.
(a) 4, 6, 8, 10, 15, 19, 22, 25
(b) 3, 3, 4, 5,5,6,6,7,7,8

Segment an is an altitude of right δabc with a right angle at a. if ab = 2, squared 5 in and nc = 1 in, find bn, an, ac.

In an improper fraction, is the numerator equal to, less than, or greater than the denominator

Data from 2005 for various age groups show that for each $100 increase in the median weekly income for whites, the median weekly income of blacks increases by $105. also, for workers of ages 25 to 54 the median weekly income for whites was $676 and for blacks was $527. (a) let w represent the median weekly income for whites and b the median weekly income for blacks, and write the equation of the line that gives b as a linear function of w. b = (b) when the median weekly income for whites is $760, what does the equation in (a) predict for the median weekly income for blacks?
