Consider the simple random sample of vehicle speeds below. Use the data to construct 3 different confidence intervals. We'll keep the sample size constant and vary the level ofconfidence, amd note the pattern that appears. Round results to 1 decimal place.* = 63 mphs = 10 mphn = 501. Construct the 80% confidence interval for vehicle speeds.2. Construct the 90% confidence interval for vehicle speeds.3. Construct the 99% confidence interval for vehicle speedsIn 1- 2 complete sentences describe the effect increasing the level of confidence on the confidence interval.
