(h) Use the probabilities you computed in part b to calculate the mean µy, the variance, o? , and the standard deviation, o, of this binomial distribution. Show that the formulas for µy , o? , and o, given in this section give the same results. (Do not round intermediate calculations. Round final answers to µy in to 2 decimal places, o ², and o, in to 4 decimal places.) ux ox^2 ox
Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.
