Question

College students were surveyed to determine how much they planned to spend in various categories during the upcoming academic year. One category is the amount spent on school supplies. The graphs below show the amount of money spent on school supplies by women and men. Two bar graphs are shown, one for men and one for women. The horizontal axis represents the amount spent on school supplies and ranges from 55 to 115. The vertical axis labels the percent, ranging from 0% to 50%. The data for the women?s graph is approximated as follows: the first bar ranges from 60 to 67.5 with a percent of 15, the second ranges from 67.5 to 75 and has a percent of 15, the third ranges from 75 to 82.5 with a percent of 30, the third ranges from 82.5 to 90 with a percent of 15, the fourth ranges from 90 to 97.5 with a percent of 25, and the last ranges from 107.5 to 115 with a percent of 5. Approximately what percent of women spend more than $105 on school supplies? Selected Answer: Correct c. 5% Answers: a. 20% b. 10% Correct c. 5% d. 15%

Expert Solution

Step 1

Given

The graphs are missing but an approximate description is given for women's bar graph is given as follows:

The x-axis consists the amount spent on school supplies which ranges from 55 to 115. The y-axis consists the percent and ranges from 0 to 50 %

The 1st bar ranges from 60 to 67.5 with a percent of 15, the 2nd bar ranges from 67.5 to 75 and has a percent of 15, the 3rd ranges from 75 to 82.5 with a percent of 30, the 4th ranges from 82.5 to 90 with a percent of 15, the 5th ranges from 90 to 97.5 with a percent of 25, and the last ranges from 107.5 to 115 with a percent of 5.
