Listed below are measured amounts of lead in the air. The EPA has established an air quality standard for lead of 1.5 mg/m3. The measurements shown below were recorded at a building on different days. Use the given values to construct a 95% confidence interval estimate of the mean amount of lead in the air 5.40,0.90,0.46,0.75,0.68,0.90 What is the confidence interval for the population mean
Find the x-bar of the sample and the s of the sample.
Calculate the standard error for 95% = 1.95*s/sqrt(6)
95% CI: x-bar-E < u < x-bar+E
