Choice I is true because a sample variance of 0 means that there is no variation or change in the values in the sample.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Choice II is not necessarily true because this sample may or may not accurately reflect/represent the overall population.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Choice III is true because the distribution is symmetrical about the equal data value.
\n" ); document.write( "
\n" );
