1. You get a $15,000 car loan for 4 years at 6.75% interest. The lender charges $250 for an origination fee (which is added to your loan amount). What is your APR?

2. You buy furniture for $2,500. You pay $300 down and the retailer finances the remainder with 36 monthly payments of $80. Calculate your APR.

4. (a) Draw a P-V diagram of a real refrigerator that uses 1 kg of HFC-134a as the working fluid.
Identify the compressor. condenser. throttle and the evaporator stages of the cycle and indicate
where heat Qc, is extracted from the cold refrigerator and where. Qa is released to the
environment. Also indicate where the refrigerant is in liquid. gas. or a mixed phase.

(b) Show that the COP = Qc(Qh -Qc) can be expressed in terms of the enthalpies at three points of the
cycle, explaining all steps of the derivation.

Question 4 (1 point)

When interpreting a job cost sheet, it can be assumed from the calculated unit cost that it would cost that much more to produce one more unit.                                 

Question 6 (1 point)

Indirect labor includes:

Question 7 (1 point)

Job sheets include a unit product cost, which can be interpreted, within the relevant range, as:

Question 9

Under/over applied manufacturing OH costs occur because:

10. Use the following information to compute the POHR for ABC , Inc for 20x2:

                                 Actual Manu OH for 20x1 = $120,000

                                Estimated Manu oh for 20x2 is estimated to be 25% higher or $150,000.

Question 10 options:

                                Actual Manu OH for 20x2 is $160,000

                                Cost driver is DL hours and the 20x2 estimate is 100,000

                                Actual DL hours for 20x2 is 110,000

4. A newspaper claims that the mean age of its current readers (population 1) has dropped 3.6 years over the last 10 years (population 2). A market researcher believes that the newspaper's claim is incorrect and plans to conduct a hypothesis test to provide evidence against the newspaper's claim. State the null and alternative hypothesis for each scenario.

The drive shaft of a dump truck is constructed of 3.5” OD x 1/4” wall round tubing made of ASTM A242 steel. The driveshaft is 65” long and is subjected to 500 lbf*ft of torque.

• What is the maximum shear stress in the drive shaft?

• What is the safety factor with respect to yielding?

• How much torque would result in a 1° twist of the drive shaft?

Question 1: Sketch A rough estimate of an IR Spectroscopy for the following Compounds

hexanal

sec-butylamine

phenylacetic acid

petan-1-ol

4-methylaniline

1.) Ten men were selected to test an exercise device by using it 4 times per week for 30 minutes. Their resting pulse rates (beats per minute) were measured before the test began, and then again after 6 weeks. Assume the differences are approximately normally distributed.

a.) At significance level ? = .05, is there sufficient evidence to conclude that exercising in this way can reduce resting pulse rates?

b.) Give a 95% confidence interval for the mean difference. Interpret your interval in context.
