The randomly selected delivery times, in minutes, of two restaurants are as follows. Which restaurant has more consistent delivery times?
Restaurant 1: 40, 37, 40, 41, 38, 46, 41, 37, 40
Restaurant 2: 42, 38, 37, 39, 38, 40, 42, 41, 40
The delivery times of both restaurants are equally consistent.
Restaurant 2 is more consistent, because the range of its delivery times is higher than that of Restaurant 1.
Restaurant 1 is more consistent, because the range of its delivery times is lower than that of Restaurant 2.
Restaurant 2 is more consistent, because the range of its delivery times is lower than that of Restaurant 1.

Restaurant 2 is more consistent, because the range of its delivery times is lower than that of Restaurant 1. Range is a measure of variability that indicates the difference between the highest and lowest values in a dataset. In this case, Restaurant 1 has a range of 9 (46-37) while Restaurant 2 has a range of 5 (42-37). A lower range suggests that the delivery times of Restaurant 2 are more consistent and less variable.
