a.
\nDoes this table describe a
\nrelative frequency distribution? Why or why not? b.
\nWhat are some of the conditions
\nfor a table to have a relative frequency distribution? 2. Listed below are
\namounts of strontium-90 (in millibecquerels) in a simple random sample of baby
\nteeth obtained from Pennsylvania residents born after 1979 (based on data from
\n\u00e2\u0080\u009cAn Unexpected Rise in Strontium-90 in U.S. Deciduous Teeth in the 1990s,\u00e2\u0080\u009d by Mangano,
\net. al., Science of the Total Environment). Construct a frequency distribution
\nwith eight classes. Begin with a lower class limit of 110, and use a class
\nwidth of 10. Cite a reason why such data are important. You may use the blank
\ntable below or create your own.155 142 149 130 151 163 151 142 156 133 138

\nabove of the amounts of strontium-90 found in baby teeth, find the following:a.

\nMean4. Construct a stemplot of
\nthe amounts of Strontium-90 from problem 3. What does the stemplot suggest
\nabout the distribution of those amounts? You may use the table below to create
\nyour stemplot.<\/p>\n

Construct a cumulative frequency distribution
\ngiven the frequency distribution table above.6. Assume that, as a
\nnewspaper reporter, you must graph data showing that increased smoking causes
\nan increased risk of lung cancer. Given
\nthat people might be helped and lives might be saved by creating a graph that
\nexaggerates the risk of lung cancer, is it ethical to construct such a graph?7. In an editorial, the Poughkeepsie
\nJournal printed this statement: “The median price–the price exactly
\nin between the highest and lowest–…”
\nDoes that statement correctly describe the median? Why or why not?8. When the Indianapolis
\nColts recently won the Super Bowl, the numbers on the jerseys of the active
\nplayers were 29, 41, 50, 58, 79,…, 10 (listed in the alphabetical order of
\nthe player’s names). Does it make sense
\nto calculate the mean of those numbers?
\nWhy or why not?9. In statistics, how do variation
\nand variance differ?10. Which do you think has
\nmore variation: the incomes of a simple random sample of 1000 adults selected
\nfrom the general population, or the incomes of a simple random sample of 1000
\nstatistics teachers? Explain.11. Listed below are the
\nannual salaries for a simple random sample of NCAA football coaches (based on
\ndata from USA Today). How does the standard deviation change if the highest
\nsalary is omitted? Compute the standard deviation of the entire list first then
\ncompute the standard deviation while omitting the highest salary.$150,000 $300,000 $350,147
\n$232,425 $360,000 $1,231,421 $810,000 $229,00012. Dr. Smith\u00e2\u0080\u0099s Generac
\ngenerator produces voltage amounts with a mean of 125.0 volts and a standard
\ndeviation of 0.3 volt. a.
\nUsing Chebyshev\u00e2\u0080\u0099s theorem, what
\ndo we know about the percentage of voltage amounts that are within 3 standard
\ndeviations of the mean? b.
\nWhat are the minimum and
\nmaximum voltage amounts that are within 3 standard deviations of the mean?13. Bao Xishun is the
\nworld\u00e2\u0080\u0099s tallest man with a height of 92.95 in. (or 7 ft, 8.95 in.). Men have
\nheights with a mean of 69.6 in. and a standard deviation of 2.8 in.a.
\nWhat is the difference between
\nBao\u00e2\u0080\u0099s height and the mean height of men?b.
\nHow many standard deviations is
\nthat (the difference found in part (a))?c.
\nConvert Bao\u00e2\u0080\u0099s height to a
\nzscore.d.
\nDoes Bao\u00e2\u0080\u0099s height meet the
\ncriterion of being unusual by corresponding to a z score that does not fall
\nbetween and 2?14. A physician routinely
\nmakes physical examinations of children. She is concerned that a three-year-old
\ngirl has a height of only 87.8 cm. Heights of three-year-old girls have a mean
\nof 97.5 cm and a standard deviation of 6.9 cm (based on data from the National
\nHealth and Nutrition Examination Survey). a.
\nUse the range rule of thumb to
\nfind the maximum and minimum usual heights of three-year-old girls. b.
\nBased on the result, is the
\nheight of 87.8 cm unusual? c.
\nShould the physician be
\nconcerned?15. Use the given sorted
\nvalues below which are the numbers of points scored in the Super Bowl for a
\nrecent period of 24 years.36 37
