An article in Nuclear Engineering International describes several characteristics of fuel rods used in a reactor owned by an electric utility in Norway. Measurements on the percentage of enrichment of 12 rods were reported as follows:
|
2.94 |
3.00 |
2.90 |
2.75 |
3.00 |
2.95 |
|
2.90 |
2.75 |
2.95 |
2.82 |
2.81 |
3.05 |
(a) Use a normal probability plot to check the normality assumption.
(b) Find a 99% two-sided confidence interval on the mean percentage of enrichment. Are you comfortable with the statement that the mean percentage of enrichment is 2.95 percent? Why?
