The retirement ages of a group of steel workers are recorded below. Construct a histogram with 4 classes using Microsoft Excel, Google Sheets, or GeoGebra. You will upload the graph in the next question. {64,60,57,63,61,64,50,62,60,56,53,62,54,60,64,53,61,58,60,64,57,56,64,61,63} What is the population mean of the data? What is the population variance? (Round to four decimal places. Note: s^2 means s2 What is the population standard deviation? (Round to four decimal places) The data is According to Chebyshev's theorem, at least 88.9% of the data falls between approximately 47.62 and ___________. (Round to the nearest hundredth
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.
