Interval for Population Save Mean 22 of 37 (12 complete) HW Score: 27.03%, 10 of 37 pts Score: 0 of 1 pt SY Instructor-created question Question Help LYNOIL Suppose data collected by observers at randomly selected intersections across the country revealed that in a sample of 250 drivers, 80 were using their cell phone. a. Give a point estimate of it, 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 it is] b. The 95% confidence interval for the population proportion at is (].). (Round to two decimal places as needed.) c. Interpret this interval. O A. We are confident that 95% of the population do not use a cell phone while driving. O B. There is a 95% percent chance that the population proportion of drivers who use cell phones is outside this interval. O C. We are confident that 95% of the population use a cell phone while driving. O D. We are 95% confident that the population proportion of drivers using cell phones is inside this interval
