Assignment 3
1. Women in the United States continue to be paid
less than men overall. Nationally, in 2007, the
median weekly earnings of female full-time wage
and salary workers totaled $614, while it was
$766 for males.
a. Fill in the blank using the data: In 2007, male fulltime wage and salary workers earned ____more
than female full-time wage and salary workers.
766-614/614 = 25% the phrase "more than
female's" indicates that females are the reference
value.
Practice “than” problem
Let’s say I make 150% more snickerdoodles on
Monday than I make on Tuesday. If I make
3000 snickerdoodles on Monday, how many
snickerdoodles do I make on Tuesday?
Practice “increase / decrease” Problem
On Wednesday I sell 1000 snickerdoodles. On
Thursday I increase my number of
snickerdoodles by 11%. How many have I
sold on Thursday?
3b. What percent of male full-time wage and
salary worker median weekly earnings does
the female median weekly earnings
represent? (This percentage is often called
the women-to-men's earning ratio.)
614/766 = 80% the phrase “percent of male”
indicates part / whole where men are the
whole.
Percentage “of” problem
If I have 1000 snickerdoodles and 78 of the
snickerdoodles have raisins. What percent of
the snickerdoodles have raisins?
Making graphs
Open the file EarnedDegreesbyLevelandGender.xls which
contains data on degrees conferred in 2006.
a. Make a single graph to answer this question: In 2006
what percentage of all degree-earning males and what
percentage of all degree-earning females earned a
Doctoral degree? Don't worry about putting in the
source. (4 points)
b. Make a single graph to answer this question: In 2006
what percentage of all those receiving a Bachelor's
degree were female and what percentage were
male? Again, don't worry about adding the source. (4
points)
