    Step-by-step explanation:

    Given that:Construct the frequency distribution table for the data on heights (cm) of 20 boys using the class intervals 130 -135, 135 -140 and so on.The heights of the boys in cm are: 140, 138, 133, 148, 160, 153, 131, 146, 134, 136, 149, 141, 155,149, 165, 142, 144, 147, 138, 139.

    Solution: Frequency distribution table can be constructed using two methods; Inclusive and exclusive.

    Normally exclusive table is constructed otherwise not mentioned.

    To construct frequency distribution table 130-135(135 not included),I.e. Exclusive type

    \begin{tabular}{|c|c|c|}\cline{1-2}Range&Frequency\\\cline{1-2}130-135&3\\\cline{1-2}135-140&4\\\cline{1-2}140-145&4\\\cline{1-2}145-150&5\\\cline{1-2}150-155&1\\\cline{1-2}155-160&1\\\cline{1-2}160-165&2\\\cline{1-2}Total&20\\\cline{1-2}\end{tabular}
