A business class surveyed college students about the cost (in dollars) of their most recent haircuts. The resulting data is summ
arized in the table below. Which data representations can you make using the information above? Select all that apply
Question 1 options:
histograms
box plots
dot plots
2. Which of the following statistics could you find given the information above (see question #1)? Select all that apply.
Question 2 options:
range
mode
standard deviation
interquartile range
3. What does the data above (see question #1) tell you about the difference in haircut costs between women and men? You may want to discuss similarities or differences in the shape, center, and spread of the data. Explain your reasoning and give mathematical evidence to support any claim that you make. If you draw any charts (or create them online) you may insert the image or add a file to your response.
4. For both women and men, the mean cost is greater than the median cost. Why do you think the data has this result? Explain your reasoning.
5. Is the mean or the median a better measure of center for the data in the table? In other words, would you fill in the blanks of this sentence with the mean values or the median values?
"The data shows that women typically spend about ____ on haircuts, and men typically spend about ____ on haircuts."
Explain the reasoning behind your choice.

Answer:
2 students study none of the subjects.
Step-by-step explanation:
Consider the attached venn diagram. First, we place that 1 student studies the three subjects. Then, we notice that 3 students study math and science, then 2 students study math and science only, since we have 1 that studies the three subjects. In the same fashion, we have that 3 students study Math and computer programming only (since they are 4 in total). Note that since 7 students study math, and we already have 6 students in our count in the math subject this implies that 1 student studies only math (the total number of students inside the math circle must add to 7).
We also have that 4 students study science and computer programming only. Which implies that we must have 3 students that study science only (10 students that study science in total) and 2 students study computer programming (for a total of 10 students). The total number of students that study none is the total number of students (18) minus the amount of students that is inside the circles (16) which is 2.
