A surgery intern has conducted a study of the sleeping habits of her colleagues and has developed a following regression equation: Y = 6 + 0.1X, where X is the number of hours working on one shift, and Y is the number of hours sleeping at night after that shift. Each work shift analyzed was between 8 and 24 hours long. All the following statements about the regression equation are true EXCEPT The minimum amount of sleep an intern would get is 6 hours For each hour working on a shift, interns slept an additional 0.1 hours The maximum amount of sleep an intern would get is 8.4 hours The minimum amount of sleep an intern would get is 6.8 hours
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.
