Consider the question of whether women tend to pay more for a haircut than do men. Some students were asked to report the total cost of their most recent haircut. Their results follow with amounts recorded to the nearest dollar.
Female: 40 20 20 15 45 20 30 55 20 17 12 30 60 40 25 60 50 20 10 0 20. 30 72 0 15
Male: 0 20 0 25 0 10 13 25 33 0 12 13 10 23 13 35 12 10
Add the data to your Ti-84 calculator, enter female prices into L1 and male prices into L2.
Create stacked boxplots using Stat Plot (2nd, y=).
1. Turn plot #1 ON, select the modified boxplot (right next to the histogram), use L1 for the female data so it will be on top.
2. Turn plot #2 ON, select the modified boxplot (right next to the histogram), use L2 for the male data so it will be on the bottom.
Use Zoom, 9 to display the two boxplots.
Using the quartiles (remember each represents 25% of the data) compare the boxplots for the haircut prices.
Select all the statements that are true when comparing the cost of haircuts for men vs women.
