The Classes of the Distribution are,

#9.5-14.5, 14.5-19.5, 19.5-24.5, 24.5-29.5, 29.5-34.5#

Explanation:

The Upper Boundary Point (UBP) of the First Class is given by the Average of #(1)# the UBP of the #1^(st)# Class and #(2)# the Lower Boundary Point of the #2#^(nd) Class.

In our case, it is #(14+15)/2=14.5#.

Proceeding on the same lines, the Classes of the Distribution are,

#9.5-14.5, 14.5-19.5, 19.5-24.5, 24.5-29.5, 29.5-34.5#
