Answer #1

Three different ways to find the probabilities for the normal distribution are:

1) Using the statistical tables, as the cumulative probabilities of the standard normal distribution are listed there and as a result probabilities of the normal distribution with any parameter values can be found out by converting it in the standard form.

2) Using the Excel software, functions which are useful are NORMSDIST and NORMSINV.

3) Empirical rule can be used to obtain the same which is also known as 68.3-95-99.7 rule.

Another type of distribution is the normal curve or sometimes called the bell curve. If a distribution has a normal curve, it is symmetrical with most of the probabilities located near the mean. Many test scores are based on a bell curve. An example of a bell curve is population IQ. The mean of the population is 100 with a standard deviation of 15.
