Answer:

Step-by-step explanation: The sample variance is calculated as follows:

Square each data point:

3^2 = 9

10^2 = 100

4^2 = 16

7^2 = 49

Add these squared values together:

9 + 100 + 16 + 49 = 164

Divide by the number of data points minus 1:

164 / (3 - 1) = 164 / 2 = 82

Rounding to one decimal place, the sample variance is 82.
