Find the variance of the given data rounded to the nearest hundredth 5.6 5.2 4.6 4.9 5.7 6.4

Step-by-step explanation:

First, find the mean:

+5.65.2+4.6+4.9+5.7+6.4

          by

           6=5.4

Now find the sum of the differences between the mean and all the points. Square those results:

5.6-5.4=.04

5.2-5.4=.04

4.6-5.4=.64

4.9-5.4=.25

5.7-5.4=.09

6.4-5.4=1

find the average of the differences:

.04+.04+.64+.25+.09+1

      by

   6 =.343
