Amy started picking blueberries at 1{:}37 \text { p. M.}1:37 p. M.1, colon, 37, start text, space, p, point, m, point, end text and finished picking at 2{:}21\text { p. M.}2:21 p. M.2, colon, 21, start text, space, p, point, m, point, end text

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
