To determine which restaurant has more consistent delivery times, we need to calculate the range of delivery times for each restaurant. The range is the difference between the maximum and minimum values in a dataset.
Restaurant 1 delivery times:
- 40, 42, 37, 41, 38, 46, 41, 37, 40, 40
Maximum = 46
Minimum = 37
Range for Restaurant 1 = 46 - 37 = 9
Restaurant 2 delivery times:
- 42, 38, 37, 39, 38, 40, 42, 41, 40
Maximum = 42
Minimum = 37
Range for Restaurant 2 = 42 - 37 = 5
Now we compare the ranges:
- Restaurant 1 has a range of 9
- Restaurant 2 has a range of 5
A lower range indicates more consistency in delivery times. Therefore, Restaurant 2 is more consistent because the range of its delivery times is lower than that of Restaurant 1.
The correct response is:
Restaurant 2 is more consistent, because the range of its delivery times is lower than that of Restaurant 1.
