Sampled from Weight-IAT
One sample T confidence interval:
μ : Mean of variable
90% confidence interval results:
Variable | Sample Mean | Std. Err. | DF | L. Limit | U. Limit |
---|---|---|---|---|---|
Sample(Age) | 31.123257 | 0.43038785 | 999 | 30.414675 | 31.831839 |
- Are conditions met to estimate the mean age for the population of IAT participants? (Be sure to support your answer as demonstrated throughout Unit 8.)
- State the confidence interval, and then interpret the confidence interval in context.
- What is the margin of error (MOE)?
- Which would be more accurate, the 90% confidence interval you found or an 85% confidence interval? Briefly explain. Which would be more precise? Briefly explain
