Commuters A recent random survey of 100 individuals in Michigan found that 78 drove to work alone. A similar survey of 140 commuters in New York found that 60 drivers drove alone to work. Find the 90% confidence interval for the difference in proportions. Use P₁ for the proportion of Michigan drivers who drive alone to work. Round your answers to three decimal places.

Question
**Commuters** A recent random survey of 100 individuals in Michigan found that 78 drove to work alone. A similar survey of 140 commuters in New York found that 60 drivers drove alone to work. Find the 90% confidence interval for the difference in proportions. Use \( \hat{p}_1 \) for the proportion of Michigan drivers who drive alone to work. Round your answers to three decimal places. --- **Explanation:** The image features a text box with spaces to input the lower and upper bounds for the confidence interval of the difference in proportions \( p_1 - p_2 \). There is also a button labeled with a multiplication symbol ("×") and one with a backward arrow symbol, possibly for calculation actions or clearing inputs.
