In working for a local retail store, you have developed the following estimated regression equation: Y= 22,167 - 412x,1 , 818x2 - 93xq - 71xy Where: o Y= weekly sales 2 X1= local unemployment rate 2 X9= weekly average high temperature @ xq4= number of activities in the local community X4= average price of gasoline per gallon 1. Based on the equation above, please provide the value for b1, b2, b3, and b4. Also, explain what these values mean by in the context of this question. For example: What does the value of 818 mean in the equation above (you aren't just mentioning if it is b1 or b2 or b3 or b4 but you would also need to explain what does those values mean by based on the equation and context)? 2. Please provide the value of bO based on the equation above. Also, explain/interpret what does the value of bg mean by in the context given. 3. What are the estimated weekly sales if the unemployment rate is 5.7%, the average high temperature is 61, there are 14 activities, and the average price of gasoline is $3.39 per gallon? See example 15-3 under Chapter 15 for some guidance
