  • Learning team paper
  • Purpose of Assignment
  • This assignment has two cases. The first case is
    on expansion strategy. Managers constantly have
    to make decisions under uncertainty. This
    assignment gives students an opportunity to use
    the mean and standard deviation of probability
    distributions to make a decision on expansion
    strategy. The second case is on determining at
    which point a manager should re-order a printer
    so he or she doesn't run out-of-stock. The second
    case uses normal distribution. The first case
    demonstrates application of statistics in finance
    and the second case demonstrates application of
    statistics in operations management.

  • Purpose of Assignment
  • The purpose of this assignment is for students to
    learn how to make managerial decisions using a
    case study on Normal Distribution. This case uses
    concepts from Weeks 1 and 2. It provides students
    an opportunity to perform sensitivity analysis
    and make a decision while providing their own
    rationale. This assignment also shows students
    that statistics is rarely used by itself. It
    shows tight integration of statistics with
    product management.
