According to study conducted in Turkey in 2018, data collected by observers at randomly selected intersections across the country reve drivers, 700 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 their cell phone whi b. Compute a 99% confidence interval for p. c. Give a practical interpretation of the interval, part b. a. A point estimate for p is b. The 99% confidence interval for p is (].). (Round to two decimal places as needed.) c. Interpret this interval. O A. We are confident that 99% of the population use a cell phone while driving. O B. There is a 99% percent chance that the true proportion of drivers who use cell phones is outside this interval. OC. We are confident that 99% of the population do not use a cell phone while driving. O D. We are 99% confident that the true proportion of drivers using cell phones is inside this interval.
