Answer:

Following are the complete solution to the given question:

Explanation:

The Lower-limit of the Ist class:
\$1

The width of the class interval:
\$200

Lower-limit for the next five-class:
\$201, \$401, \$601, \$801, \$1001

Upper-limit for the next five-class:
\$200, \$400, \$600, \$800, \$1000, \$1200

For point a:

class intervals


\$1-\$200\\\\ \$201-\$400\\\\ \$401-\$600\\\\ \$601-\$800 \\\\\$801-\$1000\\\\ \$1001-1200

For point b:

Mid-points:


\$100.5\\\\\$300.5\\\\\$500.5\\\\\$700.5\\\\\$900.5\\\\\$1000.5\\\\
