Suppose data collected by observers at randomly selected intersections across the country revealed that In a sample of 200 drivers. 180 were using their cell phone. a. Give a point estimate of it. the this driver cell phone use rate (that is. the this proportion- or population porportlon- of drivers who are using their cell phone while driving). in. Compute a 99% condence interval for n. c. Give a practical interpretation of the interval. part b. a. A point estimate for a: is D. b. The 99% condence interval for the population proportion r: is (D43). (Round to two decimal places as needed.) c. interpret this interval. 0 A. There is a 99% percent chance that the population proportion of drivers who use cell phones is outside this interval. 0 B. We are condent that 99% of the population do not use a cell phone while driving. 0 C. We are condent that 99% of the population use a cell phone while driving. 0 D. We are 99% condent that the population proportion of drivers using cell phones is inside this interval
