    30-40 \[\bcancel{||||}\] 5
    40-50 \[|||\] 3
    Q
    Group Tally Marks Frequency
    0-10 \[\bcancel{||||}|\] 6
    10-20 \[\bcancel{||||}\bcancel{||||}\] 10
    20-30 \[\bcancel{||||}\] 5
    30-40 \[||||\] 4
    40-50 \[||||\] 4
    Which of the above tables is the frequency table of the given data.

    A)  Only P

    B)         Only Q

    C)         Neither P nor Q         

    D)         Can't be determined

    Correct Answer: C

    Solution :

    The correct frequency distribution table for the given data is as follows
    Group Tally Marks Frequency
    0-10 \[\bcancel{||||}\text{  }\!\!|\!\!\text{ }\] 6
    10-20 \[\bcancel{||||}\text{  }\!\!|\!\!\text{  }\!\!|\!\!\text{  }\!\!|\!\!\text{  }\!\!|\!\!\text{ }\] 9
    20-30 \[\bcancel{||||}\] 5
    30-40 \[\text{ }\!\!|\!\!\text{  }\!\!|\!\!\text{  }\!\!|\!\!\text{  }\!\!|\!\!\text{ }\] 4
    40-50 \[\text{ }\!\!|\!\!\text{  }\!\!|\!\!\text{  }\!\!|\!\!\text{  }\!\!|\!\!\text{ }\] 4
