a.A normal distribution is any distribution that is not unusual.
\n" ); document.write( " This is not necessarily true; not unusual does not directly mean a \"normal distribution\".\r
\n" ); document.write( "\n" ); document.write( "b.The graph of a normal distribution is bell-shaped.
\n" ); document.write( " By definition, this is true.\r
\n" ); document.write( "\n" ); document.write( "c.If a population has a normal distribution, the mean and the median are not equal.
\n" ); document.write( " This may or may not be true; mean and median are different measures of central tendancy. \r
\n" ); document.write( "\n" ); document.write( "d.The graph of a normal distribution is symmetric.
\n" ); document.write( " Again, by definition, this is true.
\n" ); document.write( "
\n" );
