Convert the discontinuous data into continuous data and estimate the class marks.
The runs scored by two teams \(A\) and \(B\) on the first \(60\) balls in a cricket match are given below:
 
Number of balls Team \(A\) Team \(B\)
\(1-6\) \(2\) \(5\)
\(7-12\) \(1\) \(6\)
\(13-18\) \(8\) \(2\)
\(19-24\) \(9\) \(10\)
\(25-30\) \(4\) \(5\)
\(31-36\) \(5\) \(6\)
\(37-42\) \(6\) \(3\)
\(43-48\) \(10\) \(4\)
\(49-54\) \(6\) \(8\)
\(55-60\) \(2\) \(10\)
 
Continuous data with class mark of each class interval can be represented as follows.
