ABC Company is interested in understanding the relationship between is monthly sales with its monthly advertising expenses and monthly number of promotions (e.g. buy one item and get one item free, and similar promotions). One good way to understand how monthly advertising expenses and monthly number of promotions would be to use:
Group of answer choices
A confidence interval for monthly sales
A hypothesis test for monthly sales
ANOVA for monthly sales versus monthly advertising expenses and monthly number of promotions
A multiple linear regression model in which monthly sales would be the dependent variable and the independent variables would be monthly advertising expenses and monthly number of promotions
A control chart which depicts monthly sales, monthly advertising expenses and monthly number of promotions
Control charts, also known as Shewhart charts or process-behavior charts, are a statistical process control tool used to determine if a manufacturing or business process is in a state of control. It is more appropriate to say that the control charts are the graphical device for Statistical Process Monitoring.

Context: You own three Chick-Fil-A franchises. In your sales district, you know that the average weekly sales are $542,000. One of your stores (Clarkesville store) brought in an average of $530,000 each week in the last year. Assume that you conducted the most appropriate test and found the following: Z = 3.32 Lower Critical Value = -2.00 Upper Critical Value = 2.00 P-value = 0.0015 Level of significance = 0.05 ----------------------------------------------------------- 1a) Based on this information, which of the following...
Suppose you are interested in understanding the causal impact of having an MBA (versus just an undergraduate degree in business) on earnings. To this end, you estimate a regression of the following form: EARNINGS = 55679 + 27809(MBA) Write out the causal question/relationship that is implied by the above equation. The estimated coefficient above suggests that individuals with an MBA earn $27,809 more than those with just a business undergraduate, on average. Give an example of how omitted variable bias...
