Question

Margo is constructing a histogram to represent the following data collected on the speed at which garden snails travel. (Each data point is measured in miles per hour.)

0.03, 0.04, 0.034, 0.031, 0.038, 0.041, 0.045, 0.039, 0.037, 0.032, 0.052, 0.038, 0.029, 0.018

If Margo decides to make each bar represent a range of 0.005 miles per hour, how many data points will be in the bin representing 0.045–0.049?

Answer 1

To determine how many data points will be in the bin representing 0.045-0.049 miles per hour, we first need to calculate the lower and upper limits of this bin.

Lower limit: 0.045 - 0.005 = 0.04
Upper limit: 0.049

Now we need to count how many data points fall within this range:
0.045, 0.041, 0.038, 0.045

There are 4 data points that fall within the range of 0.045-0.049 miles per hour.
