Prompt
You are tasked with using StatCrunch and your unique IAT sample to estimate the population mean for your IAT-Score variable. My IAT is : Race-IAT
Question 1
One sample T confidence interval: : Mean of variable 80% confidence interval results:
Variable | Sample Mean | Std. Err. | DF | L. Limit | U. Limit |
---|---|---|---|---|---|
Sample(IAT-Race-Score) | 0.22438815 | 0.017456975 | 699 | 0.20199497 | 0.24678133 |
- Use StatCrunch and your unique IAT sample to estimate the meanIAT-Score for the population of IAT participants at the 80% confidence level. Copy the contents of your StatCrunch output window and paste it into your response.
- Identify the 80% confidence interval.
- Interpret your confidence interval in context.
- Can we use the StatCrunch output to find the margin of error (MOE)? If so, what is the MOE? If not, identify the missing information.
Question 2 One sample T confidence interval: : Mean of variable 95% confidence interval results:
Variable | Sample Mean | Std. Err. | DF | L. Limit | U. Limit |
---|---|---|---|---|---|
Sample(IAT-Race-Score) | 0.22438815 | 0.017456975 | 699 | 0.19011376 | 0.25866254 |
- Use StatCrunch and your unique IAT sample to estimate the meanIAT-Score for the population of IAT participants at the 95% confidence level.Copy the contents of your StatCrunch output window and paste it into your response.
- Identify the 95% confidence interval.
- Interpret your confidence interval in context.
- Can we use the StatCrunch output to find the margin of error (MOE)? If so, what is the MOE? If not, identify the missing information.
