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 = $1.752 and standard deviation o = $1.122.Click the icon to view the frequency distribution for the tax rates.Frequency distribution of cigarette tax ratesTax RateFrequency0.00-0.4970.50-0.99131.00–1.4971.50–1.992.00–2.492.50–2.993.00–3.493.50–3.994.00–4.491Co Co (o LO
