The population of persons infected by Covid-19 virus is known to increase at a tate proportional to the number of persons presently infected by the virus. After 5 days 1000( D) infected persons are olserved in the city and after 25 days. 4000(D + 1) infected persons. Find i) an expression for the approximate mumber of infected persons in the city at any time t, and O the approximate mumber of persons initially infected in the city.
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.
