Expert Answer

Step 1

Given information:

Sample size (n) = 28

Confidence level = 0.90

Sample variance = 9.61

Step 2

Sample standard deviation is square root of sample variance. So,

Sample variance (s) = /s = 19.61 = 3.1

Step 3

Significance level = 1- Confidence level

                              = 1- 0.90

                              = 0.10
