      Standard Deviation = What do you notice about your solutions to parts b and c? Use binomial table and graph for n = 5, p = 0.90 to answer the following: What is the shape of the binomial distribution when p = 0.90? Use the binomial table and your TI-calculator to find the mean and standard deviation of this binomial probability distribution.

      Here are the formulas for the mean and standard deviation of the binomial: and . Now we can return to the earlier example and do parts D and E. When calculating the mean and standard deviation for 1000 free-throws you may only think the mean makes any sense, but you can also make some sense of the standard deviation.

      Using the calculator, binomcdf (n, p, X) is the cumulative density function of the binomial distribution. So, binomcdf (10, .1, 2) = .9298091736. Binomial mean and standard deviation: If a certain widget has a 75% chance of functioning correctly, then how many should work out of a lot of 100? Logically 75 should work. In fact, the formula for ...
