Here's how to determine the class intervals from the given midpoints:\r
\n" ); document.write( "\n" ); document.write( "1. **Find the Class Width:**\r
\n" ); document.write( "\n" ); document.write( " The class width is the difference between consecutive midpoints. In this case:\r
\n" ); document.write( "\n" ); document.write( " 22 - 17 = 5
\n" ); document.write( " 27 - 22 = 5\r
\n" ); document.write( "\n" ); document.write( " The class width is consistent (5), which is what we expect.\r
\n" ); document.write( "\n" ); document.write( "2. **Determine the Boundaries:**\r
\n" ); document.write( "\n" ); document.write( " * **For the midpoint 17:**
\n" ); document.write( " * Subtract half the class width from the midpoint to get the lower boundary: 17 - (5/2) = 17 - 2.5 = 14.5
\n" ); document.write( " * Add half the class width to the midpoint to get the upper boundary: 17 + (5/2) = 17 + 2.5 = 19.5\r
\n" ); document.write( "\n" ); document.write( " * **For the midpoint 22:**
\n" ); document.write( " * Lower boundary: 22 - (5/2) = 22 - 2.5 = 19.5
\n" ); document.write( " * Upper boundary: 22 + (5/2) = 22 + 2.5 = 24.5\r
\n" ); document.write( "\n" ); document.write( " * **For the midpoint 27:**
\n" ); document.write( " * Lower boundary: 27 - (5/2) = 27 - 2.5 = 24.5
\n" ); document.write( " * Upper boundary: 27 + (5/2) = 27 + 2.5 = 29.5\r
\n" ); document.write( "\n" ); document.write( "3. **Write the Class Intervals:**\r
\n" ); document.write( "\n" ); document.write( " * 14.5 - 19.5
\n" ); document.write( " * 19.5 - 24.5
\n" ); document.write( " * 24.5 - 29.5
\n" ); document.write( " \n" ); document.write( "
\n" );
