The linear regression model was conducted to establish the relationship between depression scores, income in thousands, and job satisfaction of employees. The analysis was conducted using an alpha level of .05. The output indicates that the model explains 73% of the relationship between the variables (R-square = 0.733) (Field, 2018). Job satisfaction is taken as the response variable when modeling relationships. The correlation analysis indicates that both income in thousands and depression scores are positively related to job satisfaction. However, the relationship between the variables is not statistically significant since the p-values are greater than .05.

Include confidence intervals in your output and explain what this means.

The confidence levels for the model parameters indicate that the beta values or the intercepts are more likely to fall. For the depression scores, the 95% confidence interval for the intercept is between -0.02114 and 0.091491. For income in thousands, the 95% confidence interval for the intercept is between -0.00837 and 0.157358. The confidence interval for the overall model intercept is between -2.52792 and 4.493543.
