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 11 = $1.621 and standard dewation cr = $1.049. a Click the icon to view the frequency distribution for the tax rates. The population mean is $ 1667'. (Round to three decimal places as needed.) The population standard deviation is $ 1.!01'. (Round to three decimal places as needed ) Compare these results to the values found using the actual data. O A. The grouped mean is slightly larger, while the grouped standard deviation is slightly smaller. 0 B. The grouped mean is slightly smaller, while the grouped standard deviation is slightly larger. O C. The grouped values are both slightly smaller. O D. The grouped values are both slightlv larger.
