Extracted text: According to study conducted in Turkey in 2018, data collected by observers at randomly selected intersections across the country revealed that in a sample of 50 drivers, 20 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 while driving). b. Compute a 95% confidence interval for p. c. Give a practical interpretation of the interval, part b. a. A point estimate for p is. b. The 95% confidence interval for p is ( . ). (Round to two decimal places as needed.) c. Interpret this interval, O A. We are 95% confident that the true proportion of drivers using cell phones is inside this interval. O B. There is a 95% percent chance that the true proportion of drivers who use cell phones is outside this interval. Oc. We are confident that 95% of the population use a cell phone while driving. O D. We are confident that 95% of the population do not use a cell phone while driving.
