A pоll wаs cоnducted аsking emplоyees аnd students at a large college, "Do you believe that there is enough parking available at the college?" In a random sample of 150 employees, 67 believed that there was enough parking. In a random sample of 320 students, 170 believed that there was enough parking. Assume that the conditions are met to construct a confidence interval. Choose the best answer in each case. Where rounding is necessary round to three decimal places. 1. What is the point estimate of the difference in the proportions of employees and students that believe that there is enough parking at the college? [pt] 2. Find the 95% confidence interval for the difference in the proportions of employees and students that believe that there is enough parking. We are 95% confident that the difference in the proportions of employees and students that believe that there is enough parking is between [lower] and [upper]. Since the interval [is] we [conclude].
