The U.S. Census Bureau keeps a runningclock totaling the U.S. population. On September 20, 2012, thetotal was increasing at the rate of 1 person every 12 sec. The populationfigure for 8:11 p.m. EST on that day was 314,419,198. At this rate, what will the U.S. population be at 8:11 p.m. EST on September 20, 2019?
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.
