Question

tamara measures the heights of 8 family members to the nearest eighth inch and creates a data set shown.

{66 1/2, 62 3/4, 67, 71/1/8, 70 1/2, 68 7/8, 65 1/4, 67 3/8}

What os the range of the heights, in inches, of the tamara's family members

Answer 1

To find the range of the heights, we need to subtract the smallest value from the largest value in the data set.

The smallest value is 62 3/4 inches and the largest value is 71 1/8 inches.

Converting these fractions to a common denominator of 8, we have:
62 3/4 = (8*62 + 3)/4 = 495/8
71 1/8 = (8*71 + 1)/8 = 569/8

So, the range of the heights is (569/8) - (495/8) = 74/8 = 9 1/8.

Therefore, the range of the heights of Tamara's family members is 9 1/8 inches.
