  1. A sample of eight resistors of a certain type resulted asfollows:

                 43, 46, 42, 38, 40, 46, 49, 40

Compute the following:

  1. Sample Mean
  2. Sample Variance
  3. Sample Median
  4. 25% Percentile
  5. 75% Percentile
  1. Consider the following pdf:

     P(X = 0) = 0.48, P(X = 1) =0.39, P(X = 2) = 0.12, and P(X= 3) = 0.01.

Find the following:

  • Do the plot for P(X) and F(X)
  • F(0) = P(X ? 0) =
  • F(1) = P(X ? 1) =
  • F(2) = P(X ? 2) =
  • F(3) = P(X ? 3) =
  • P(1 ? X ? 2) =
  • ?x =
  • ?x2 =
