To find the median delivery time for each pizza shop, we first need to arrange the delivery times in ascending order:
For Pizza Shop 1: 15, 18, 20, 21, 22, 23, 24, 28
Median = (20 + 21) / 2 = 20.5
For Pizza Shop 2: 16, 17, 18, 20, 20, 21, 25, 38
Median = (20 + 21) / 2 = 20.5
Both pizza shops have the same median delivery time of 20.5 minutes. Therefore, based on the median delivery time, we cannot determine which pizza shop has the fastest delivery time.
Kat and Joshua want to know which pizza shop has the fastest delivery time. Kat took a random sample of 8 delivery times from pizza shop 1 over a period of six months. Joshua did the same for pizza shop 2. The delivery times (in minutes) for each pizza shop are shown in the following table.
Pizza Shop 1 Pizza Shop 2
18 20
23 17
15 16
22 38
21 21
24 20
28 18
20 25
