JUST PART TWO PLEASE! 1. Videoworld is a discount store that sells color televisions. The monthly demand for color television sets is 100. The cost per order from the manufacturer is $600. The carrying cost is $64 per set each year. Assume a year has 360 working days. Determine the following values rounding to the nearest integer (answer them using only numbers without any sign such as the dollar sign, comma, ...): Q1. The optimal quantity per order: Q2. The...

The following question examines the prices of televisions. In this question, we’re going to consider regressions of the form: pricei = β0 + β1sizei + β2size2i + β3UHDi + εi Where pricei is the retail price of the television in dollars, sizei is the size of the TV screen in inches, and UHDi is a binary {0,1} indictor for whether or not the television supports ultra-high definition (versus conventional high definition). We run the regression two different ways. The coefficients...
