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= $1.885 and standard deviation o = $1.115. E Click the icon to view the frequency distribution for the tax rates. The population mean is S (Round to three decimal places as needed.)

Scores on the SAT test have a mean of 1518 and a standard deviation of 325. Scores on the ACT test have a mean of 21.1 and a standard deviation of 4.8. Which of the following choices is not true? O A. An ACT Score of 17.0 has a z-score of -0.85. O B. An SAT score of 1490 has a z-score of -0.09. Oc. The ACT score of 17.0 is relatively better than the SAT score of 1490. O D. The SAT Score of 1490 is relatively better than the ACT score of 17.0.

The mean is 146 and the standard deviation is 35. A score of 41 is how many z-scores below the mean?

Draw by hand or in Excel fully labelled curves on a common scale to represent two sets of scores where: b. Mean = 50, Standard Deviation = 2, Mean = 50, Standard Deviation = 5. CUA
