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( "------------
