      Paste the binomial distribution graph to the bottom of this lab under the binomial distribution table. To produce binomial probability distributions and graphs for p = 0.50 and p = 0.90 (keep n =5) change the third argument in cell B2 to 0.50 and 0.90 and use the fill handle to fill in the remaining values in the table.

      Mean, Variance, and Standard Deviation for the Binomial Distribution (5.3) If we have the probability distribution in the editor of the calculator we can use the calculator by doing STAT – CALC, 1-VarStat L1, L2. Otherwise we can use these formulas for binomial distributions. Remember that the variance is the square of the standard deviation:
