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=​$1.762 and standard deviation σ=​$1.112.

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=​$1.762 and standard deviation σ=​$1.112.

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 = $1.762 and standard deviation o = $1.112. Click the icon to view the frequency distribution for the tax rates. Frequency distribution of cigarette tax rates The population mean is $ Tax Rate Frequency 0.00-0.49 7 (Round to three decimal places as needed.) 0.50-0.99 14 The population standard deviation is $. 1.00–1.49 (Round to three decimal places as needed.) 1.50–1.99 2.00–2.49 6. Compare these results to the values found using the actual data. 2.50–2.99 3.00–3.49 6. O A. The grouped mean is slightly larger, while the grouped standard deviation is slightly smaller. 3.50-3.99 4.00–4.49 1 B. The grouped values are both slightly smaller. C. The grouped values are both slightly larger. O D. The grouped mean is slightly smaller, while the grouped standard deviation is slightly larger. Print Done
