**Current Attempt in Progress** To calculate a 90% confidence interval for the difference in proportions (p1 - p2), follow these steps: 1. **Assume the results come from random samples:** - Sample 1 proportion (p1) = 0.17 with sample size (n1) = 500 - Sample 2 proportion (p2) = 0.064 with sample size (n2) = 210 2. **Determine the best estimate for p1 - p2, the margin of error, and the confidence interval.** 3. **Rounding:** - Best estimate: Round to two decimal places. - Margin of error and confidence interval: Round to three decimal places. 4. **Enter your results:** - Best Estimate: \[ ____ \] - Margin of Error: \[ ____ \] - Confidence Interval: From \[ ____ \] to \[ ____ \] 5. **Save or submit your work:** - Options: "Save for later" or "Submit Answer" - Note: Auto submission is enabled; submissions can take up to 10 minutes. 6. **Number of attempts:** - 0 of 6 attempts used. Make sure to follow the instructions carefully to ensure accuracy in your confidence interval calculations.
