The heights of 220 summer camp attendees are normally distributed with a mean of 62.4 inches and a standard deviation of 3.7 inches. About how many attendees could be expected to be shorter than 55 inches?
\n" ); document.write( "---------
\n" ); document.write( "z(55) = (55-62.4)/3.7 = -2
\n" ); document.write( "P(x < 55) = P(z < -2) = normalcdf(-100,-2) = 0.0228
\n" ); document.write( "Ans:: 0.0228*220 = 5 when rounded up
\n" ); document.write( "--------------
