Verdi studied music in ______ where Italy's most important opera house is located. When a composer writes new music for each stanza of a poem the form is known as ______. Name two writers of lyric poetry that were favored by romantic composers. T/F Schubert was the first great master of the romantic art song.
The normal distribution is defined by the following equation: Normal equation. The value of the random variable Y is: where X is a normal random variable, Î¼ is the mean, Ï is the standard deviation, Ï is approximately 3.14159, and e is approximately 2.71828.Y = { 1/[ Ï * sqrt(2Ï) ] } * e. The random variable X in the normal equation is called the normal random variable.e enter these values into the Normal Distribution Calculator and compute the cumulative probability. The answer is: P(X. 365) = 0.90. Hence, there is a 90% chance that a light bulb will burn out within 365 days. Example 2. Suppose scores on an IQ test are normally distributed.
Clearly, given a normal distribution, most outcomes will be within 3 standard deviations of the mean. To find the probability associated with a normal random variable, use a graphing calculator, an online normal distribution calculator, or a normal distribution table. The total area under the normal curve is equal to 1. 2  The probability that a normal random variable X equals any particular value is 0. 3  The probability that X is greater than a equals the area under the normal curve bounded by a and plus infinity (as indicated by the non-shaded area in the figure below).
