Question

Suppose 111 people who shopped in a special t-shirt store were asked the number of t-shirts they own costing more than $19 each.Thefollowing relative frequency histogram shows the results of the survey.

Answer 1

Given the shown histogram

The total interviewed people = 111

The total of people that own less than 3 special T-shirts is given by the first 2 columns in the histogram

`5+17=22`

22 people own less than 3 T-shirts that cost more than $19 each

since we have 111 people, the percentage is given by

`(22)/(111)*100`
`0.19819*100`
`19.819\%`

Round to the nearest whole percentage

the percent is 20%
