In a study to predict job satisfaction among employees in the banking sector, three predictors: Pay, job security and freedom were used. The output for the Pearson's correlation for the four variables is given below:

Required:

Provide a brief interpretation of the results in table 2b                                          

Based on the findings presented in table 2c, is the overall regression model significant at the 5% level? Explain?                                                                               Write down the fitted regression function from the output in table 2d?                     

Formulate appropriate hypothesis for this study?                                                   

Interpret how Pay, job security and freedom explain the variation of the response variable Y?
