If you were to calculate a confidence interval using a confidence level of 0.9 and then calculated a second confidence interval using the same data but changed the confidence level to 0.95, would the interval be more narrow or wider?
narrow
wider
it would depend on the standard deviation
it would depend on the degree of certainty sought
| 1. | narrow | |
| 2. | wider | |
| 3. | it would depend on the standard deviation | |
| 4. | it would depend on the degree of certainty sought |
Solution
wider, as the reason the alpha value directly proportional to confidence level
