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 of confidence, amd note the pattern that appears. Round results to 1 decimal place. I = 63 mph s = 10 mph n = 50 1. 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 speeds In 1- 2 complete sentences describe the effect increasing the level of confidence on the confidence interval.
