A, B, C please. Included is my answer for 3A Problem #4 - The mean number of air conditioning units assembled per month by Freeze, Inc. is 750 and the standarddeviation is 100 units.If the number of air conditioning units assembled per month follows a normal distribution, calculate thea.probability of Freeze, Inc. to assemble a quantity of air conditioning units greater than the monthly break-even pointcalculated in problem 3-a.b.An improved assembling process is proposed to Freeze, Inc. to reduce the variable cost from $500 perunit to $400 per unit., increase the mean number of air conditioning units assembled per month from 750 to 850 andreduce 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 conditioningunits that Freeze Inc. must sell every month to break-even, discuss and justify if you would recommend the processimprovement initiative.с.If the number of air conditioning units assembled per month still follows a normal distribution after theimplementation of the improvements described on item (b), calculate the probability of Freeze, Inc. to assemble aquantity 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 undercertainty, 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 thecoefficient of correlation are related and how would you use them in regression analysis. Problem #3:Rnow that at break-even, revenue must be equatto cost.Here we have a variable cost of $5004a manthiyFixed Cost of sa50, 0OA:)/owecan represent it as a Function C(x)-560X+250,000,wewhere x is the 'number of units sold.we aiso know they sell eacah unit at lo00,30 revenuefuntion RY)=1000xAt break even point, total revenuelo00X=500X+250,000total costsolving we get,500x= 250,000%3DX=200,000/500 =5003o Freeze Inc. must sell S00 unito per month to meetbreak-eURn conditions.

Given information: μ=750, σ=100Break even point=500Given in Q 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. 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 b.
