The frequency distribution was obtained using a class width of 0.5 for data on cigarette tax rates. Use the frequency distribution to approximatethe population mean and population standard deviation. Compare these results to the actual mean u = $1.598 and standard deviation o = $1.024.Click the icon to view the frequency distribution for the tax rates.Frequency distribution of cigarette tax ratesTax RateFrequency0.00–0.4950.50-0.99131.00–1.491.50–1.9972.00–2.492.50-2.993.00–3.493.50–3.9914.00–4.492
