Question

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 μ=​$1.536 and standard deviation σ=​$0.949.

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 u = $1.536 and standard deviation o = $0.949.
