Question

It's been hours & no one has answered me. I need A, B, C & included is my answer to 3A 

**Problem #4** – The mean number of air conditioning units assembled per month by Freeze, Inc. is 750 and the standard deviation is 100 units. a. If the number of air conditioning units assembled per month follows a normal distribution, calculate the probability of Freeze, Inc. to assemble a quantity of air conditioning units greater than the monthly break-even point calculated in problem 3-a. b. An improved assembling process is proposed to Freeze, Inc. to reduce the variable cost from $500 per unit to $400 per unit, increase the mean number of air conditioning units assembled per month from 750 to 850 and reduce the standard deviation to 90 units. As a result of the improvements, monthly fixed costs would go up from $250,000 to $300,000. Once these improvements are implemented, calculate the new number of air conditioning units that Freeze Inc. must sell every month to break-even, discuss and justify if you would recommend the process improvement initiative. c. If the number of air conditioning units assembled per month still follows a normal distribution after the implementation of the improvements described in item (b), calculate the probability of Freeze, Inc. to assemble a quantity of air conditioning units greater than the new monthly break-even point. Now that you know this probability, would you change your recommendation? Justify. **Discussion Question #1** – Using your "own words", discuss the differences among decision making under certainty, decision making under risk, and decision making under uncertainty. Provide an example for each one of them. **Discussion Question #2** – Using your "own words", discuss how the coefficient of determination and the coefficient of correlation are related and how you would use them in regression analysis.

**Problem #3:** **A.)** We know that at break-even, revenue must be equal to cost. - Here we have a variable cost of $500 and a monthly fixed cost of $250,000. - So we can represent it as a function, \( C(x) = 500x + 250,000 \), where \( x \) is the number of units sold. - We also know they sell each unit at $1000, so the revenue function \( R(x) = 1000x \). - At the break-even point, total revenue = total cost: \[ 1000x = 500x + 250,000 \] Solving we get: \[ 500x = 250,000 \] \[ x = \frac{250,000}{500} = 500 \] - So Freeze Inc. must sell 500 units per month to meet break-even conditions.
