4. Linear Regression Suppose we have data giving the square footage (in hundreds) of houses in Long Island along with their prices (in millions). 1 Footage (in hundreds) Price (in million dollars) 0.5 0.7 1.0 1.25 1.3 1.4 1.6 1.0 1.2 1.3 2.0 1.5 2.1 1.9 A real estate agency wants to build a regression model to predict the price of properties per square footage. Let's help them by performing a linear regression $y = \beta_0 + \beta_1x$. (a) Find the $\beta_0$ and $\beta_1$ using the formulas seen in class. No need to standardize the data. Show all intermediary calculations. Round all to the nearest hundredths (2 decimals). $\beta_0 = \frac{1}{n}\sum_{i=1}^{n}y_i - \beta_1\frac{1}{n}\sum_{i=1}^{n}x_i$ $\beta_1 = \frac{\sum_{i=1}^{n}x_iy_i - \frac{1}{n}\sum_{i=1}^{n}y_i\sum_{i=1}^{n}x_i}{\sum_{i=1}^{n}x_i^2 - \frac{1}{n}(\sum_{i=1}^{n}x_i)^2}$ (b) What would be the predicted y of a new house with footage = 1.1?
