      Using Table A (table of standard normal probabilities) or your calculator, find the proportion of observations from a standard normal distribution that satisfies each of the following statements. In each case, sketch the normal curve and shade the area under the curve that is the answer to the question.

      Procedure for Using a Normal Distribution to Approximate a Binomial Distribution. Establish that the normal distribution is a suitable approximation to the binomial distribution by verifying np ( 5 and nq ( 5. Find the values of the parameters µ and ( by calculating µ = np and ( = npq. Identify the discrete value of x (the number of successes).

    • ASSESSING THE APPROXIMATE NORMALITY OF DATA

      BEFORE NAVIGATOR: After the normal curve has been studied, classes can be presented with data sets which may or may not come from a normal distribution. The question then becomes, what characteristics must data exhibit in order to be considered approximately normal? Some of the questions we need to ask about the data are: Is the data symmetrical?

      This is a great way to make a demonstration of an approximate normal distribution. However to create a large sample takes a long time. Using Fathom, you can simulate this event hundreds even thousands of time in a very short amount of time. Open a new Fathom Workspace. Drag a collection, , from the shelf into the workspace.

      Since the total area under the curve of a normal distribution is 1, this probability can be calculated by finding the area under the normal curve for that interval. To find areas under any normal distribution, you can either use your calculator or tables. We will use Z to denote the standard normal distribution and will consider 3 cases:
