The data set shows the ages of guests on a recent tour of a museum: 34, 18, 29, 60, 44, 51, 65, 68. A. What is the five-number summary of the data? Show your work.

B. How could the museum curator use this information to improve sales at the gift shop?

I already did part A I just need help on part B

The five-number summary is

Min: 18 Max: 68 Median: 47.5

Q1: 31.5 Q3:62.5

Step-by-step explanation:

Given the data:

34, 18, 29, 60, 44, 51, 65, 68.

Ordered data :

18, 29, 34, 44, 51, 60, 65, 68

The five number summary :

Sample size = 8

Minimum = 18

Lower quartile (Q1) = 1/4 (n+1) = 9/4 = 2.25

(2nd + 3rd term) / 2

= (29 + 34) / 2 = 31.5

Using calculator :

Median (Q2) = 47.5

Upper quartile (Q3) = 62.5

Maximum = 68

2.) With the information above, the museum curator could use this to guide their stock preference by stocking up gifts suitable for adults and youths, stockingbup with children's gift may be a bad options as visitors are atleast 18 years of age.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
