Homework Help: Very easy question (Clarification)

  1. Feb 2, 2014 #1
    1. The problem statement, all variables and given/known data

    There was study made, with a histogram shown below where the maximum number of calls made were 80, of the students who sent messages, 75% sent X or less, determine X.

    2. Relevant equations

    X/80= 0.75

    3. The attempt at a solution

    Now unless i'm missing something (which I'll proceed to lash myself if that's true) the answer should be 60, yet the book says 62.

    Is this a misprint or am i missing something?

    Are you able to upload the histogram you were provided?

    I should have read the book answer more clearly, i just read it and it says 75% sent LESS than 62 messages, it didn't say 62 was the answer (i.e X)

    Sorry folks false alarm, nothing to see here.
