Use the binomial table and your TI-calculator to find the mean and standard deviation of this binomial probability distribution. (Enter the probability column without rounding) Mean = Standard Deviation = Now use the binomial formulas to find the mean and standard deviation when n = 5 and p = 0.50. Mean = 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:

Normal Distribution. A normal distribution. follows a bell-shaped curve. We use the two parameters . mean, μ, and . standard deviation, σ, to distinguish one normal curve from another. For shorthand we often use the notation . N (μ, σ) to specify that a distribution is normal (N) with some mean (μ) and standard deviation (σ). To do at ...

X bar is our sample mean and Σx is the sum of all of the entries. We still need to calculate the median. To help us obtain the median we obviously need to put the data into order. The calculator does this for us. Press STAT and select #2 SortA (this tells the calculator to sort the data in ascending order). Again we are back at the main screen.
