Question

The randomly selected delivery times, in minutes, of two restaurants are as follows. Which restaurant has more consistent delivery times? This table presents the randomly selected delivery times (in minutes) for two restaurants, allowing for comparison of their performance. Restaurant 1 Restaurant 2 40 42 37 38 40 37 41 39 38 38 46 40 41 42 37 41 40 40 (1 point) Responses Restaurant 1 is more consistent, because the range of its delivery times is lower than that of Restaurant 2. 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. The delivery times of both restaurants are equally consistent. 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.

Answer 1

To determine which restaurant has more consistent delivery times, we should calculate the range of delivery times for both restaurants.

Restaurant 1 Delivery Times: 40, 42, 37, 38, 40, 37, 41, 39, 38, 38

• Minimum: 37
• Maximum: 42
• Range = Maximum - Minimum = 42 - 37 = 5

Restaurant 2 Delivery Times: 46, 40, 41, 42, 37, 41, 40, 40

• Minimum: 37
• Maximum: 46
• Range = Maximum - Minimum = 46 - 37 = 9

Conclusion: Restaurant 1 has a range of 5 and Restaurant 2 has a range of 9. Since a lower range indicates more consistency in delivery times, we can conclude that:

Restaurant 1 is more consistent, because the range of its delivery times is lower than that of Restaurant 2.
