Answer:

The sample variance is approximately 32.58, and the sample standard deviation is approximately 5.71.

Explanation:

Mean = (17 + 10 + 2 + 6 + 9) / 5 = 44 / 5 ≈ 8.8

(17 - 8.8)^2 ≈ 74.76

(10 - 8.8)^2 ≈ 1.44

(2 - 8.8)^2 ≈ 46.24

(6 - 8.8)^2 ≈ 7.84

(9 - 8.8)^2 ≈ 0.04

Sum ≈ 74.76 + 1.44 + 46.24 + 7.84 + 0.04 = 130.32

Sample Variance = Sum / (n - 1) = 130.32 / (5 - 1) ≈ 32.58

Sample Standard Deviation = √(Sample Variance) ≈ √32.58 ≈ 5.71 (rounded to two decimal places)

So, the sample variance is approximately 32.58, and the sample standard deviation is approximately 5.71.
