Question Help 3.3.7-T 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 = $1.663 and standard deviation o = $1.059 Click the icon to view the frequency distribution for the tax rates.

1. Using the following data, perform the following analysis. (a) Develop a grouped frequency distribution table. (b) Calculate the mean and standard deviation of the grouped data. 6, 9, 10, 19, 33, 24, 29, 8, 30, 21, 12, 35, 9, 18, 21, 31, 13, 15, 32, 10, 20, 14, 21, 7, 12.
Find the standard deviation, s, of sample data summarized in the frequency distribution table below by using the formula below, where x represents the class midpoint, f represents the class frequency, and n represents the total number of sample values. Also, compare the computed standard deviation to the standard deviation obtained from the original list of data values, 11.1 .
(3) The following frequency distribution table summarizes the amount of tar (img) in non-filtered cigarettes from a simple random sample. Find the mean and the standard deviation of the data. Also compare the computed mean and standard deviation to the actual ones by using the original data values, which are mean = 21.1 gm and s = 3.2 mg.
