Suppose you work for a software company and you would like to estimate the market value of your company. You hypothesize that the market value of a software company (response variable) is a linear function of its earnings (explanatory variable). To test this, you collect data on the earnings and market value of 4 companies in your industry. This results in the following data: Company earnings ($mm) market cap ($mm) Unicorn 12 70 Bolt 2 24 PsiCo 100 700 Big 50 450   You fit a linear regression to these data. The company you work for (BizStatCo) has earnings of $50 million. What is the model's estimate of the market cap for BizStatCo (i.e., what is the y^)?
