The randomly selected delivery times, in minutes, of two restaurants are as follows. Which restaurant has more consistent delivery times?

Answer 1

To determine which restaurant has more consistent delivery times, we can compare the ranges of the delivery times of the two restaurants.

Restaurant A delivery times: 25, 27, 28, 29, 30, 31, 32, 33, 35, 36
Range = 36 - 25 = 11 minutes

Restaurant B delivery times: 28, 29, 30, 31, 33, 34, 35, 36, 37, 39
Range = 39 - 28 = 11 minutes

Both restaurants have the same range of delivery times, so they have the same level of consistency in their delivery times.
