17 Chapter 1.2 Slope of the tangent line, Instantaneous Rate of Change and Derivative The population of a certain city is given by the function f(x) = x³, where x is years since 2000 and the population is measured in thousands of people. 13. a) Find the average rate of change in the population between the years of 2000 and 2018. b) Find the instantaneous rate of change in population in the year 2018 and interpret this answer.
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.
