Bob's range in times is ___ and his friend's range in times is ____. The range shows that _____ times are more consistent since it is ____.

Answer 1

To calculate the range for both Bob's times and his friends' times, we first need to find the minimum and maximum values in each dataset.

Bob's Times:

• Data: 51, 48, 45, 44, 47, 50, 44, 47, 45, 43, 49, 44, 43, 44
• Maximum: 51
• Minimum: 43
• Range = Maximum - Minimum = 51 - 43 = 8

Friends' Times:

• Data: 52, 56, 45, 49, 44, 44, 43, 42, 43, 41
• Maximum: 56
• Minimum: 41
• Range = Maximum - Minimum = 56 - 41 = 15

Now we can fill in the answers:

Bob's range in times is 8 and his friend's range in times is 15. The range shows that Bob's times are more consistent since it is smaller.
