Expert Answer

Step 1

Given data of  multiple births in United States in past 10 years. We need to determine range, variance and standard deviation of these following data sets.

fullscreen
Step 2

Now we arrange all the dats sets in increasing order and find the minimum and maximum values in all the three mentioned datasets.

Range of a Triplets = Maximum value - Minimum value = 7110-5877 = 1233

Range of Quadruplets = Maximum value - Minimum value = 512-345 = 167

Range of Quintuplets = Maximum value - Minimum value = 91-46 = 45

Step 3

In order to find the variance, here  we  find the sample means with respect to each data set. Mean is calculated by adding all the data points ...
