Finding the mean, midpoint and sd

  1. Sep 18, 2009 #1
    1. The problem statement, all variables and given/known data

    The Acme Chocolate Factory produces 40 different types of chocolate candies. An individual sample of each candy was weighed tot he nearest gram.
    weight - Types of candies
    0-4 - 7
    5-9 - 14
    10-14 - 10
    15-19 - 4
    20-24 - 2
    25-29 - 3

    3. The attempt at a solution
    The midpoints: 2, 7, 12, 17, 22, 27
    Mean: On the cal. I type midpoints into L1 and Candies L2. It comes to 10.63.
    Standard Deviation: 7.07
    Variance: 7.07^2 = 49.98
