Consider this scenario: A cereal packing company where the content of cereal boxes must have a mean of 368 grams to satisfy the labeling on the boxBecause it is expensive to welgh every box produced at the factory, a sample of boxes is used to estimate the actual meanAfter analyzing the data sample, the operations manager must decide whether or not the manufacturing process is working as expected. Suppose a sample of 100 boxes is taken from thousands produced during an 8-hour shift and the standard deviation () of the cereal-filling process is 12what is the standard error of the mean? Use the equation, /square root ofn where n is the sample size. Enter your result as a value with one digit after the decimal point (e,g,1,7), .
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.
