The following measurements (in picocuries per liter) were recorded by a set of carbon monoxide detectors installed in a waste disposal facility: 487.4,473.8,534.3 Using these measurements, construct a 95% confidence interval for the mean level of carbon monoxide present in the facility. Assume the population is approximately normal.

step 1: sample mean round two decimal places

step 2 sample standard deviation two decimal places

step 3 find critical vaue of confidence level round three decimal places
