Create a graphical analysis for categorical variables (e.g., property type, presence of a garage) and numerical variables (e.g., total interior space, property age). Comment on the key findings. (10 marks) For statistical analysis involving a hypothesis test for comparing the average interior space of properties with and without a garage (independent two-sample t-test): Formulate the null and alternative hypotheses. State your statistical decision using the significant value () of 5%. (10 marks) Evaluate the performance of a simple linear regression analysis using property age as the independent variable and sale price as the dependent variable. Describe and explain your process for variable selection. Justify your choices with regression data analysis. (10 marks) Check the model assumptions for the simple linear regression model and identify common violations. (10 marks) Evaluate the performance of a multiple linear regression analysis using three numerical variables (e.g., property age, interior space, and land size) to predict sale price. Describe and explain your process for variable selection. Justify your choices with regression data analysis. (10 marks) Check the model assumptions for the multiple linear regression model and identify common violations. (10 marks) Compare the performance of the simple linear regression (Model 1) and the multiple linear
