A data set consisting of two types of illnesses, bacterial and viral, and their respective durations is summarized in the table below. TYPE OF ILLNESS DURATION Viral Bacterial Total Short 23 47 70 Moderate 42 38 80 Long 10 6 16 Total 75 91 166 a) Construct the conditional distribution of the variable DURATION for Viral Illnesses. Your answer should be a distribution, not a single value. b) Construct the conditional distribution of the variable DURATION for Bacterial Illnesses.Your answer should be a distribution, not a single value
Correlation
Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
Linear Correlation
A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.
Regression Analysis
Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as predictors. Regression analysis is one of the methods to find the trends in data. The independent variable used in Regression analysis is named Predictor variable. It offers data of an associated dependent variable regarding a particular outcome.

a) Construct the conditional distribution of the variable DURATION for Viral Illnesses. Your answer should be a distribution, not a single value.
b) Construct the conditional distribution of the variable DURATION for Bacterial Illnesses.Your answer should be a distribution, not a single value
Given data is as follows:
|
Duration/ Type of Illness |
Viral | Bacterial | Total |
| Short | 23 | 47 | 70 |
| Moderate | 42 | 38 | 80 |
| Long | 10 | 6 | 16 |
| Total | 75 | 91 | 166 |
