Predicting Mоnthly Sаles fоr а New Cоffee Shop Assume there is а multiple regression model to predict a coffee shop’s monthly sales (in thousands of dollars) based on advertising spending, customer satisfaction rating, and social media engagement: Sales = 5 + 0.9 * Advertising Spending + 1.8 * Satisfaction Rating + 0.04 * Social Media Engagement Advertising Spending is measured in thousands of dollarsSatisfaction Rating is on a 1 to 10 scaleSocial Media Engagement is a score based on likes, comments, and shares per month 1. Interpretation of the slope coefficients (2 * 2 = 4 points) 1.1. What does the coefficient for "Advertising Spending" mean in this context? 1.2. What does the coefficient for "Satisfaction Rating" mean in this context? 2. Interpretation of the intercept (2 points) What does the intercept represent, and does it make logical sense in this scenario, and why? 3. Prediction (2 points) Assume this coffee shop scenario falls within the range of data used to fit the model.If the shop spends 3 thousand dollars on advertising, has a satisfaction rating of 8, and has a social media engagement score of 600, what monthly sales would the model predict?
