The ABC Company runs two shifts, from 8:00 am to midnight. Backups and system maintenance are performed between midnight and 8:00 am. For each of the following scenarios, determine whether the company’s current backup procedures enable it to meet its recovery objectives, and explain why:
Scenario 1:
Recovery point objective = 24 hours
Daily backups at 3:00 a.m., process takes 2 hours
Copy of backup tapes picked up daily at 8:00 a.m. for storage off-site
Scenario 2: Company makes daily incremental backups Monday through Friday at 3:00 a.m. each night. Company makes full backup weekly, on Saturdays at 1:00 p.m.
Recovery time objective = 2 hours
Time to do full backup = 3 hours
Time to restore from full backup = 1 hour
Time to make incremental daily backup = 1 hour
Time to restore each incremental daily backup = 30 minutes
Scenario 3: Company makes daily differential backups Monday through Friday at 3:00 a.m. each night. Company makes full backup weekly, on Saturdays, at 1:00 p.m.
Recovery time objective = 6 hours
Time to do full backup = 4 hours
Time to restore from full backup = 3 hours
Time to do differential daily backups = 1 hour on Monday, increasing by 30 minutes each successive day
Time to restore differential daily backup = 30 minutes for Monday, increasing by 15 minutes each successive day

Net Realizable Value Method, Decision to Sell at Split-off or Process Further
Pacheco, Inc., produces two products, overs and unders, in a single process. The joint costs of this process were $60,000, and 15,000 units of overs and 36,000 units of unders were produced. Separable processing costs beyond the split-off point were as follows: overs, $20,000; unders, $23,040. Overs sell for $2.00 per unit; unders sell for $3.14 per unit.
Required:
1. Allocate the $60,000 joint costs using the estimated net realizable value method.
| Allocated Joint Cost | |
| Overs | $ |
| Unders | $ |
2. Suppose that overs could be sold at the
split-off point for $1.80 per unit. Should Pacheco sell overs at
split-off or process them further?
Overs should not be processed further as there
will be $_________ more profit if sold at
split-off.

Pacheco, Inc., produces two products, overs and unders, in a single process. The joint costs of this process were $60,000, and 14,000 units of overs and 36,000 units of unders were produced.

Tel-Skein is a call centre which fields all queries by customers of a national bank. Calls that are put through to operators who specialise in queries regarding ‘Lost or Stolen Debit Cards’ occur at random at a mean rate of 90 per hour.
(i) What is the probability distribution, including its parameter(s), of the number of calls arriving in this part of the call centre during a two-minute interval? (There is no need to calculate any probabilities in this part of the question).
(ii) Data have been collected on numbers of customers calling this part of the call centre in 100 two-minute periods and are summarised below. Use an appropriate test to investigate whether or not the data are consistent with your answer to part (i). Explain your method and conclusions carefully.
| number of calls arriving in two minutes period | |||||||
| o | 1 | 2 | 3 | 4 | 5 | >=6 | |
| frequency | 6 | 21 | 24 | 21 | 15 | 5 | 8 |
(iii)On Sundays, Tel-Skein runs a ‘skeleton-shift’ (i.e. it employs a reduced number of operators). As a result, operators specialising in ‘Lost or Stolen Debit Cards’ also have to field calls regarding ‘Bill Payments’. Calls regarding ‘Bill Payments’ occur at random at a mean rate of 150 per hour.
Assuming the call rate for ‘Lost or Stolen Debit Cards’ is unchanged, what is the probability that, during a one-minute period on Sundays, there will be between 3 calls and 5 calls; and what is the probability that the gap between calls will exceed 30 seconds?

A baseball coach reviews the number of runs hit per game for the past several seasons. Since the team plays so many games, he selects a random sample of 10 games and records the number of runs scored in each game. The average number of runs scored is 7 with a standard deviation of 3.1 runs.
Compute the margin of error given a confidence level of 99%. (Use a table or technology. Round your answer to three decimal places.)

Total fixed costs in the period were budgeted at $100,000 and were
absorbed on the basis of labour hours worked.
In May 2010 the following results were achieved.
40,000kg of wood were bought at a cost of $196,000, this produced 19,200 cricket bats. No inventory of raw materials is held. The labour was paid for 62,000 hours and the total cost was $694,000. Labour worked for 61,500 hours.
Variable overheads in the period were $67,000.
The sales price was reduced to protect the sales levels. However, only 18,000 cricket bats were sold at an average price of $65.
Total fixed costs in May were $107,000.
Required : Calculate the sales, materials, labour, variable overheads, fixed overheads variances and any other appropriate variances in as much detail as possible.
