The frequency distribution was obtained using a class width of 0.5 for data on cigarette tax rates. Use the frequency distribution to approximate the population mean and population standard deviation. Compare these results to the actual mean =$1.713 and standard deviation o= $1.056. H The population mean is $ 1.755. (Round to three decimal placer as needed.) The population standard deviation is $ Frequency distribution of cigarette tax rates Tax Rate 0.00-0.49 0.50-0.99 1.00-1.49 1.50-1.99 2.00-2.49 2.50-2.99 3.00-3.49 3.50-3.99 4.00-4.49 Frequency 5 12 8 7 7 5 3 32 2
