Question

suppose one hundred eleven people who shopped in a special t - shirt store were asked the number of t - shirts they own costing more than $19 each.
bar graph with x - axis number of t - shirts costing more than $19 each (values 1,2,3,4,5,6,7) and y - axis relative frequency (values 0, 5/111, 10/111, 20/111, 30/111, 40/111). bars: 1: 5/111, 2: 17/111, 3: 23/111, 4: 39/111, 5: 25/111, 6: 2/111, 7: ~0
find the percent of people that own at most three t - shirts costing more than $19 each (round your answer to a whole number) %

Explanation:

Step1: Identify frequencies for at most 3

"At most 3" means 1, 2, 3. Their frequencies: \( \frac{5}{111} \), \( \frac{17}{111} \), \( \frac{23}{111} \).

Step2: Sum the frequencies

Total relative frequency: \( \frac{5 + 17 + 23}{111} = \frac{45}{111} \).

Step3: Convert to percentage

Multiply by 100: \( \frac{45}{111} \times 100 \approx 40.54\% \), round to whole number.

Answer:

41%
