The town of KnowWearSpatial, U.S.A. operates a rubbish waste disposal facility that is overloaded if its 4680 households discard waste with weights having a mean that exceeds 27.22 lb/wk. For many different weeks, it is found that the samples of 4680 households have weights that are normally distributed with a mean of 26.95 lb and a standard deviation of 12.13 lb. What is the proportion of weeks in which the waste disposal facility is overloaded? P(M > 27.22) = Enter your answer as a number accurate to 4 decimal places. NOTE: Answers obtained using exact z-scores or z-scores rounded to 3 decimal places are accepted. Is this an acceptable level, or should action be taken to correct a problem of an overloaded system? Yes, this is an acceptable level because it is unusual for the system to be overloaded. No, this is not an acceptable level because it is not unusual for the system to be overloaded.m

An auditor for a hardware store chain wished to compare the efficiency of two different auditing techniques. To do this he selected a sample of nine store accounts and applied auditing techniques A and B to each of the nine accounts selected. The number of errors found in each of techniques A and B is listed in the table below:
| Errors in A | Errors in B |
| 25 | 11 |
| 28 | 17 |
| 26 | 19 |
| 28 | 17 |
| 32 | 34 |
| 30 | 25 |
| 29 | 29 |
| 20 | 21 |
| 25 | 30 |
Select a 90% confidence interval for the true mean difference in
the two techniques.
a) [0.261, 8.627]
b) [-4.183, 4.183]
c) [2.195, 6.693]

Lipto Biomedic has credit sales of $740,000 yearly with credit terms of net 60 days, with an average collection period of 75 days. Lipto is considering offering a 3 percent discount for payment in 10 days. They would use the cash generated from the reduced receivables to reduce their bank loans which cost 8%. Assume ALL of the customers take advantage of the 3/10 terms. Use the following table to calculate the costs and benefits for Lipto and make decision at the bottom.
| Cost(s) |
Benefit(s) |
B) As mentioned above, Ipto Biomedic can borrow from its bank at 8% to take a cash discount offered by one of its suppliers. The terms of cash discount are 2/155 net 90. Should the Lipto borrow the funds? Why? Why not? Show all your work...
C) Lipto Biomedic sells its product for $32 each. The carrying costs of the inventory are $1.50 per unit and its costs Lipto $30 per order in purchasing agent time. If the raw materials can only be ordered by the "gross" (1 gross = 12 dozen = 144 items) What is the economic order quantity?
