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

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 =$1.66 and standard deviation =$1.076.

Tax rate	Frequency
0.00-0.49	5
0.50-0.99	15
1.00-1.49	7
1.50-1.99	6
2.00-2.49	6
2.50-2.99	5
3.00-3.49	4
3.50-3.99	1
4.00-4.49	3
