Example: If X is a normal variable with mean 100, its c.d.f. F(x) should look like: • Sometimes we do not know the distribution of our variable of interest. • The empirical distribution function (e.d.f.) is an estimator of the true c.d.f. – it can be calculated from the sample data.

Discrete example: Consider a bag of 5 balls numbered 3,3,4,9, and 11. Take a ball out at random and note the number and call it X, X is a random variable. Let’s complete the probability distribution of X. X 3 4 9 11 P(X) Lets also make a graph of the values of X (imagine the balls are now cubes with base 1 and we stack them as follows ...

Suppose you wish to generate the probability distribution for a binomial random variable for which there are 5 trials (n = 5) and the probability of success is .3 (p = .3). Do the following: Input the possible values for X in the spreadsheet: 2. Move to the cell next to X = 0 (cell B2 in this example…

This is another example of a uniform probability distribution which was discussed earlier. It is constant in an interval and zero elsewhere. The cumulative distribution function is just the integral of the density function from - ( to t. So F(t) = 0 for t < 0 and F(t) = t/5 for 0 ( t ( 5 and F(t) = 1 for t > 5.

Standard deviation in the scope of this course is population standard deviation because it is a calculation on the full probability distribution. In the example of the number of heads in three coin tosses: V ar X =0.75 . σ = 0.75 . σ =0.866 (to nearest thousandth) NESA exemplar question.

A probability table is a row-and-column presentation of marginal and joint probabilities. Refer to the Football problem (No. 1 of the Twelve Practice Problems below), which deals with two types stance by player X (the rows), and two types of plays (the columns).

Note: ( is the parameter of the distribution. Example 1.1. The mean number of bacteria per millilitre of a liquid is known to be 4. Assuming that the number of bacteria follows a Poisson distribution, find the probability that, in 1 ml of liquid, there will be . no bacteria. 4 bacteria. less than 3 bacteria.
