Plz help with question 5(abc)

Use the following case to answer the question. When modeling the retirement age of employees, the data analytics team at the Catanni Telecom has used simple linear regression analysis. The model built by the data analytics team uses the natural logarithm (In) of the amount in the retirement savings account of each employee at age 40 as the predictor, while the retirement age of the employee is the outcome (response) variable. The training data used for building the model had 200 retired professionals. Below is the fitted model with the estimated regression parameters. The regression diagnostic analyses did not show serious violations of underlying assumptions. Assume that both of the estimated parameters are statistically significant at 0.05 level.
