Heights of men on a baseball team have a​ bell-shaped distribution with a mean of 173 cm and a standard deviation of 6 cm. Using the empirical​ rule, what is the approximate percentage of the men between the following​ values?\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "a. 155 cm and 191 cm
\n" ); document.write( "b. 167 cm and 179 cm\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "a.
\n" ); document.write( "___​% of the men are between 155 cm and 191 cm.
\n" ); document.write( "​(Round to one decimal place as​ needed.)
\n" ); document.write( "b.
\n" ); document.write( "___% of the men are between 167 cm and 179 cm.
\n" ); document.write( "​(Round to one decimal place as​ needed.) \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "z-score = (raw-score minus mean) / standard deviation.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "mean is 173 and standard deviation is 6.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "z1a = (155 - 173)/6
\n" ); document.write( "z1b = (191 - 173)/6\r
\n" ); document.write( "\n" ); document.write( "z2a = (167 - 173)/6
\n" ); document.write( "z2b = (179 - 173)/6\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "solve for z in each of these equations to get:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "z1a = -3
\n" ); document.write( "z1b = 3\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "z2a = -1
\n" ); document.write( "z2b = 1\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the empirical rule says:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "68% will fall within the first standard deviation, 95% within the first two standard deviations, and 99.7% will fall within the first three standard deviations of the mean. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "It is also referred to as the Three Sigma Rule, or the 68-95-99.7 Rule.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "your solutions are:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "a.
\n" ); document.write( "99.7​% of the men are between 155 cm and 191 cm.
