Chapter 5, Problem 25SE(choose chapter or problem)
Refer to Exercise 24. A sample of six repair records for a different type of 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? If so, compute it. If not, explain why not.

QUESTION:
Refer to Exercise 24. A sample of six repair records for a different type of 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? If so, compute it. If not, explain why not.
ANSWER:
Solution
Step 1 of 1
Here we have to tell whether we can find the 95% confidence for the population standard deviation interval for the given 6 sample values
The given values are 93, 97, 27, 79, 81, 87
For finding that we have to draw the scatter plot
