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
Restaurant 2 is more consistent, because the range of its delivery times is higher than that of Restaurant 1.
• The delivery times of both restaurants are equally consistent.
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.
To determine which restaurant has more consistent delivery times, we can calculate the range for each restaurant. The range of the delivery times is the difference between the maximum and minimum delivery times.
For Restaurant 1:
Maximum delivery time = 46 minutes
Minimum delivery time = 37 minutes
Range = 46 minutes - 37 minutes = 9 minutes
For Restaurant 2:
Maximum delivery time = 42 minutes
Minimum delivery time = 37 minutes
Range = 42 minutes - 37 minutes = 5 minutes
Therefore, Restaurant 2 is more consistent in terms of delivery times because it has a smaller range of delivery times compared to Restaurant 1.
