    The number 3 question are we to find the mode
    Cause i don’t understand the one dp stuff

    1. allsaintssecschool

      Find the mode but let it be correct to 1 decimal place

      1. Raphael

        Yes. u are right

    2. Raphael

      The question is in oder. First, u draw the histogram of the data and from it u obtain the mode of the distribution to one decimal place as required.
