Hi! I know I am asking a lot since this is a huge question, but I was wondering if anyone could help or walk me through it. I totally understand if you do not want to help. But I am really confused and any help at all would be amazing. Thank you!
You are writing an article on gaming systems for your school newspaper. You take a survey of 250 people
ages 13 to 18 and ask whether they have a home gaming system, a portable gaming system, or no gaming
system. The results of your survey are shown in the matrix below.
Age:13 14 15 16 17 18
No gaming: 18 12 8 6 12 16
Portable gaming: 5 5 4 9 7 6
Home gaming: 12 22 26 32 24 26
a) Make a histogram that represents the number of students who have gaming systems (either home or
portable). Is the histogram uniform, symmetric, or skewed?
b) Display some or all of the data using a different representation. Explain your choice.
c) If a person needed to know as much specific data as possible, what kind of data display would you show
the person? Why?
d) What is the experimental probability that the next person you survey does not have a gaming system?
