14 11. Cigarette Tar A simple random sample of 25 filtered 100-mm cigarettes is obtained,that the tar content of filtered 100-mm cigarettes has a standard deviation different frommanufacture aircraft altimeters. A simple random sample of new altimeters resulted in theand the tar content of each cigarette is measured. The sample has a standard deviation oflisted in Data Set 1 of Appehave a mean of 47.6 cents and a standard deviation of 33.5 cents. If the amounts from 0 centsmethod has errors with a standard deviation greater than 32.2 ft, which was the standirdminute.3.7 mg (based on Data Set 10 in Appendix B). Use a 0.05 significance level to test lon ofa3.2 mg.which is the standard deviation for unfiltered king-size cigarettes.12. Analysis of Pennies In an analysis investigating the usefulness of pennies tportions of 100 randomly selected credit card charges from the author arerecorded, and theyto 99 cents are all equally likely, the mean is expected to be 49.5 cents and the ponulasstandard deviation is expected to be 28.866 cents. Use a 0.01 significance level to ter aclaim that the sample is from a population with a standard deviation equal to 28,866 cIf the amounts from 0 cents to 99 cents are all equally likely, is the requirement of a nomaldistribution satisfied? If not, how does that affect the conclusion?13. Ages of Race Car Drivers Listed below are the ages (years) of randomly selected race cardrivers (based on data reported in USA Today). Most people in the general population have agesthat vary between 0 and 90 years, so use of thecral population have a standard deviation of 22.5 years. Use a 0.01 significance level to test theclaim that the standard deviation of ages of all race car drivers is less than 22.5 years.rule of thumbthatsuggestsagesin the gen-range32 32 33 33 41 29 38 32 33 23 27 45 52 29 2514.
