Question: You are doing research on air quality in southern Ontario. For downtown Toronto, you have three air quality measurements. The amount of air particulates per cubic meter in the three measurements is found to be: 82.10, 75.75 and 75.44 mg. Use a 99% confidence interval to estimate the mean amount of air particulates (per cubic meter) in Toronto’s downtown core. HINT: To save time on calculations, you can use: \(\sum{{{x}^{2}}}\) = 18170
