Solve the below problem:
Q: Three different simple random samples were selected from the same normally distributed population and used to construct the following confidence interval estimates for µ.
| Interval |
Lower Confidence Interval |
Upper Confidence Interval |
| A |
37.0 |
52.0 |
| B |
38.0 |
50.0 |
| C |
38.4 |
48.4
|
Suppose each sample standard deviation was the same and that all three sample sizes were the same. Which interval has the most confidence associated with it?
