    Find mean from frequency table


    I am required to find the mean of the above table. I am not sure how to go about it. I thought to set midpoints for each range, getting the middle value between both, but I am unsure if that is correct or what to do next if it is.

    Hopefully someone can point me in the right direction. Cheers.
