Provide a step-by-step explanation. Instructor-created questionQuestion HelpSuppose data collected by observers at randomly selected intersections across the country revealed that in a sample of 250 drivers, 50 were using their cell phone.a. Give a point estimate of T, the true driver cell phone use rate (that is, the true proportion- or- population porportion- of drivers who are using their cell phone while driving).b. Compute a 95% confidence interval for n.c. Give a practical interpretation of the interval, part b.a. A point estimate for t is.b. The 95% confidence interval for the population proportion a is (,).(Round to two decimal places as needed.)c. Interpret this interval.A. We are confident that 95% of the population use a cell phone while driving.B. We are confident that 95% of the population do not use a cell phone while driving.OC. There is a 95% percent chance that the population proportion of drivers who use cell phones is outside this interval.O D. We are 95% confident that the population proportion of drivers using cell phones is inside this interval.

a) Given that there are 250 sample of drivers. Among 250 drivers, 50 were using their cell phone.…
