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 p = $1.715 and standard deviation 6 =$1.114 Click the icon to view the frequency distribution for the tax rates. The population mean is $. (Round to three decimal places as needed.) The population standard deviation is $]. (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 smaller, while the grouped standard deviation is slightly larger. O B. The grouped values are both slightly larger. O C. The grouped values are both slightly smaller. O D. The grouped mean is slightly larger, while the grouped standard deviation is slightly smaller.
