1. A researcher collected data from car shoppers about their favorite car color. He asked 250 people about their favorite vehicle color and the survey revealed the following: 32% said blue, 24% said white, 20% said red, 18% said black, and 4% said silver.

(a) What percent preferred a color other than blue, white, red, black, or silver?
(3 pts: 2 for answer, 1 for showing work)

(b) How many more people said their favorite color is white compared to those who said black? (3 pts – 2 for answer, 1 for showing work)

(c) Draw and label a circle graph showing the responses to the survey. Be sure to include a section for “Other”. Be sure your circle graph is labeled, and the percentages are in proportion to the whole. (2 pts – 1 for correctly showing percentages and 1 for labeling)

A)2%  B)15 more   *DID NOT DO C*

Step-by-step explanation:

A)

32+24+20+18+4   (add up the percentages)

=98%

100-98   (find what percentage of people did NOT like the given colors)

=2%

B)

24% of 250  (we want people, not percent)

=60

18% of 250 (Again, people, not percent)

=45

60-45    (we want the difference between the two=subtract)

=15  (15 more people preferred white, rather than black)
