A sample of six repair records for a different type of fiber optic component was drawn. The repair costs, in dollars, were as follows. 93 97 27 79 81 87 Would it be appropriate to compute a 95% confidence interval for the population standard deviation of the costs

The answer is "This is the right thing. There might be a surface sample which indicates that the population is not regular".

Step-by-step explanation:

When the community is ordinary or a biosensor, a normal distribution could be calculated for the dependent variable. Data shows chi-squared distributions of n-1 degrees - of - freedom about the dependent variable.

Chi-square was its precise outcome for the data set, while chi-square is a close estimate for non-normal information. So, we should also calculate CI for uncommon information. Throughout the case of an outlier, however, data refers to non because as mean tends to move in a skewed direction to the outer surface.
