The weight of oranges growing in an orchard is normally distributed with a mean weight of 5 oz. and a standard deviation of 1.5 oz. Using the empirical rule, determine what interval would represent weights of the middle 68% of all oranges from this orchard. \n" ); document.write( "---- \n" ); document.write( "Note:: If 68% is in the middle there must be two tails of 16% each. \n" ); document.write( "------ \n" ); document.write( "Find the z-value limiting those two tails:: \n" ); document.write( "invNorm(0.16) = -1 and -invNorm(0.16) = +1 \n" ); document.write( "---- \n" ); document.write( "Lower weight limit = 5-1*1.5 = 3.5 oz \n" ); document.write( "Upper weight limit = 5+1*1.5 = 6.5 oz \n" ); document.write( "------------ \n" ); document.write( "Cheers \n" ); document.write( "Stan H.\r \n" ); document.write( "\n" ); document.write( "--- \n" ); document.write( " |
