Problem 40E
The following five values are a sample: 11, 6, 10, 6, and 7.
a. Compute the sample variance.
b. Determine the sample standard deviation.
ANSWER:
Solution
Step 1 of 2
a) We have to find the sample variance
The given sample is 11, 6, 10, 6, 7
Here the sample mean
=(11+6+10+6 +7)/5
=40/5
=8
The sample variance is denoted by
The sample variance
=
=
=5.5
Hence the sample variance is 5.5
