All dates are specified as manufacturing planning calendar days. Assume that all jobs arrive on day 275.

Assume each job starts at the beginning of the day and finishes at the end of the day​ (a job that begins on day 275 and takes 8 days will finish on day​ 282, and the next job begins in the morning of day​ 283). Compute all times based on initiating work on day 275.

​a) Using the FCFS​ (first come, first served​ ) decision rule for sequencing the​ jobs, the order is​ (assume that jobs came in the order in which they are listed in the​ table): ___A-B-C-D-E___

*The average tardiness​ (job lateness) for the sequence developed using the FCFS rule​ = ______ days ​(round your response to two decimal​ places).

*Calculate the percentage utilization for the sequence developed using the FCFS rule = _______ % (round your response to two decimal​ places).

​b) Using the EDD​ (earliest due​ date) decision rule for sequencing the​ jobs, to determine the order of the jobs​ (to resolve a​ tie, use the order in which the jobs were​ received).

*Under the EDD​ rule, jobs are scheduled in the order in which they are due. Arrange the due dates in ascending order to perform the scheduling: _______

*Calculate the average tardiness​ (job lateness) for the sequence developed using the EDD rule = _________ days (round your response to two decimal​ places).

*Calculate the percentage utilization for the sequence developed using the EDD rule = _______ % (round your response to two decimal​ places).

​c) Using the SPT​ (shortest processing​ time) decision rule for sequencing the​ jobs, determine the order of the jobs​ (to resolve a​ tie, use the order in which the jobs were​ received).

*Under the SPT​ rule, jobs are scheduled based on the ordering of the processing time with the shortest one first. Arrange the processing times in ascending order to perform the scheduling: _____________

*Calculate the average tardiness​ (job lateness) for the sequence developed using the SPT rule = _______ days (round your response to two decimal​ places).

*Calculate the percentage utilization for the sequence developed using the SPT rule = ________ % (round your response to two decimal​ places).

​d) Using the LPT​ (longest processing​ time) decision rule for sequencing the​ jobs, determine the order of the jobs​ (to resolve a​ tie, use the order in which the jobs were​ received).

*Under the LPT​ rule, jobs are scheduled based on the ordering of the processing time with the longest one first. Arrange the processing times in descending order to perform the scheduling: _________

*Calculate the average tardiness​ (job lateness) for the sequence developed using the LPT rule =_____ days (round your response to two decimal​ places).

*Calculate the percentage utilization for the sequence developed using the LTP rule = ______ % (round your response to two decimal​ places).

2013 6% 5%

a. Calculate the average arithmetic return and standard deviation for MSFT and the S&P500.

b. Assuming you are a risk averse investor and expect the next 12 months to be similar to the past twelve months. If you had to make a choice between investing in either MSFT or the S&P 500 which one would you choose? Why?

c. Assuming you could hold 50% of your funds in each security would this change your decision? (please calculate the average return and standard deviation of the equally weighted portfolio – assume a correlation coefficient of .5).

You are provided with the following information for Bridgeport Inc., which purchases its inventory from a supplier for cash and has only cash sales. Bridgeport uses the average cost formula in a perpetual inventory system. Increased competition has recently reduced the price of the product.

Date Explanation Units Unit Cost/Price
Apr. 1 Beginning inventory 50 $84
6 Purchases 110 87
8 Sales (130 ) 116
15 Purchases 120 71
20 Sales (120 ) 98
27 Purchases 20 62

1. Prepare all journal entries for the month of April for Bridgeport, the buyer

2.Determine the ending inventory amount for Bridgeport

3. On April 30, Bridgeport learns that the product has a net realizable value of $51 per unit. What amount should ending inventory be valued at on the April statement of financial position

We assume that our wages will increase as we gain experience and become more valuable to our employers. Wages also increase because of inflation. By examining a sample of employees at a given point in time, we can look at part of the picture. How does length of service (LOS) relate to wages? The data here (data45.dat) is the LOS in months and wages for 60 women who work in Indiana banks. Wages are yearly total income divided by the number of weeks worked. We have multiplied wages by a constant for reasons of confidentiality.

(a) Plot wages versus LOS. Consider the relationship and whether or not linear regression might be appropriate. (Do this on paper. Your instructor may ask you to turn in this graph.)

(b) Find the least-squares line. Summarize the significance test for the slope. What do you conclude?

Wages = +  LOS
t =
P =   


(c) State carefully what the slope tells you about the relationship between wages and length of service.

As increase 1 unit in the independent variable (wages), the average change in the dependent variable (Los) is ??//.

This answer has not been graded yet.



(d) Give a 95% confidence interval for the slope.

a. Itot(parallel) = 1/4 × Itot(series)

b. Itot(parallel) = 1/2 × Itot(series)

c. Itot(parallel) = 2 × Itot(series)
