Question 1 1. Which IAT data set are you working with? 2. 3. Use StatCrunch and your unique IAT sample to estimate the mean age for the population of IAT participants at the 90% confidence level. Copy the contents of your StatCrunch output window and paste them into your response. (No need to type anything here - just copy and paste the contents of your StatCrunch output window.) 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.) 4. State the confidence interval, and then interpret the confidence interval in context. 5. What is the margin of error (MOE)? 6. 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. One sample T confidence interval: μ: Mean of variable 90% confidence interval results: Variable Sample(IAT-Weight-Score) Sample Mean Std. Err. DF L. Limit U.
