A research was conducted relating job satisfaction (measured as a score based on a rating scale from 1 to 10, with 1 as the lowest and 10 as the highest) to years on the job. Assume that the simple linear regression model obtained from the data in the study is significant and is given as Job satisfaction = 5.64 + 0.1107 Years on the Job. a.) Interpret the regression slope. b.) For someone who has been working for 5 years on the job, what would be expected of his/her job satisfaction rating? c.) For a worker who has been on the job for 25 years, what would be expected of his/her job satisfaction rating
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.

Job satisfaction = 5.64 + 0.1107 Years on the Job.
a.) Interpret the regression slope.
b.) For someone who has been working for 5 years on the job, what would be expected of his/her job satisfaction rating?
c.) For a worker who has been on the job for 25 years, what would be expected of his/her job satisfaction rating?
