Suppose data collected by observers at randomly selected intersections across the 250 drivers, 50 were using their cell phone. a. Give a point estimate of p, the true driver cell phone use rate (that is, the true proportion of drivers who are using cell phone while driving). b. Compute a 90% confidence interval for p. c. Give a practical interpretation of the interval, part b. a. A point estimate for p is 0.2 b. The 90% confidence interval for p is (). (Round to two decimal places as needed.) c. Interpret this interval. ant 90% of the population use a cell phone while driving.
