rubbish waste disposal facility that is overloaded if its 4703 households discard waste with weights having a mean that exceeds 27.19 lb/wk. For many different weeks, it is found that the samples of 4703 households have weights that are normally distributed with a mean of 26.92 lb and a standard deviation of 12.54 lb.What is the proportion of weeks in which the waste disposal facility is overloaded? P(M > 27.19) =
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.
