- A(n) variable is calculated from within the model. A(n). endogenous; endogenous endogenous; exogenous exogenous; endogenous exogenous; exogenous none of the above variable can never be taken as given.The soft goods department of a large department store sells 184 units per month of a certain large bath towel. The unit purchase cost of a towel to the store is $2.5 and the cost of placing an order has been estimated to be $11. The store's inventory carrying cost is 33% of the purchase cost of the goods. Suppose that the demand rate is a constant and the EOQ model is used. What is the optimal annual cost of placing orders and holding inventory?i. List all the endogenous and exogeneous variables in the model.
- A large company in the communication and publishing industry hs quantified the relationship between the price of one of its products and the demand for this product as Price = 160 -0.01 xDemand for an annual printing of this particular product. The foxed costs per year (ie. per printing) = $4T 000 and the variable cost per unit = $35. What is the maximum profit that can be achieved? What is the unit price at this point of optimal demand? Demand is not expected to be more than 7,000 units per year. The maximum profit that can be achieved is S. (Round to the nearest dolar.) The unit price at the point of optimal demand is S per unit (Round to the nearest cent)Explain when fixed effects, random effects or pooled OLS models are usually used.This is model question.

- Question 19 Lot's say you run a simulation and figure out that your sample bs one of the likely sampies that could have come from a DGP of 0. What would that mean? • A That is a good sign. Our model is good and probably explains a lot of variation. • B This is a bad sign for our model because a DGP of 0 means there is no relationship between the explanatory and outcome variable. • C This does not mean anything for our model. We have to run supernova to find out about how good our model is. • Dit depends on what our b Type Markdown and LaTeX: a Question 20 14 MacBook ProUsing the fixed-time period inventory model, and given an average daily demand of 287 units , 4 days between inventory reviews, 5 days for lead time, 141 units of inventory on hand, a "z" of 1.96, and a standard deviation of demand over the review and lead time of 2 units, which of the following is the order quantity?What is centeris paribus assumptions
