Wilson Publishing Company produces books for the retail market. Demand for a current book is expected to occur at a constant annual rate of 7,400 copies. The cost of one copy of the book is $11.50. The holding cost is based on an 18% annual rate, and production setup costs are $150 per setup. The equipment with which the book is produced has an annual production volume of 25,000 copies. Wilson has 250 working days per year, and the lead time for a production run is 15 days. Use the production lot size model to compute the following values. (Round your answers to two decimal places.)

(a)

Minimum cost production lot size

(b)

Number of production runs per year

(c)

Cycle time

(d)

Length of a production run (in days)

days

(e)

Maximum inventory

(f)

Suppose that Westside Auto, a manufacturer of automobile generators with D = 13,000 units per year, C_h = (2.00) (0.20) = $0.40, and C_o = $25, decided to operate with a backorder inventory policy. Backorder costs are estimated to be $5 per unit per year. Identify the following. (Assume 250 working days per year. Round your answers to two decimal places.)

Specifications:

This project will have two data classes and a tester class.

Design:

Create a solution for this programming task. You will need to have the following parts:

• Text file to store data between runs.
• Two classes that implement the given interfaces. You may add methods beyond those in the interfaces
• A tester class that tests all of the methods of the data classes.

Here are the interfaces for your data classes:

package project1;

import java.util.ArrayList;

public interface Person {

       public void setId (String id);

       public String getId ();

       public void setName (String name);  

       public String getName ();

       public void addTHING (String THING);

       public void removeTHING (String THING);

       public ArrayList<String> getTHINGs ();

       public String toString();

}

package project1;

import java.util.ArrayList;

public interface PersonDataManager {

       public void addPerson (Person p);

       public Person getPerson (String id);
       public ArrayList<String> getTHINGSDESCRIPTION (ArrayList<String> THINGs); //for this, its just a set of descriptions for THINGs (just use THINGdescription1, 2, 3 for each one and ill do the rest

       public void writeToFile ();

       public void writeToFile (String fn);

       public String toString();

}

For ace's, they are either going to be a 1 or 0 for 10 different attributes. I only need a basic skeleton for the code and can do the rest but I am struggling with the starting point

Periodic Inventory by Three Methods

Dymac Appliances uses the periodic inventory system. Details regarding the inventory of appliances at January 1, purchases invoices during the next 12 months, and the inventory count at December 31 are summarized as follows:

Required:

1. Determine the cost of the inventory on December 31 by the first-in, first-out method.

If the inventory of a particular model comprises one entire purchase plus a portion of another purchase acquired at a different unit cost, use a separate line for each purchase. If units are in inventory at two different costs, enter the units PURCHASED MOST RECENTLY first.

2. Determine the cost of the inventory on December 31 by the last-in, first-out method.

If the inventory of a particular model comprises one entire purchase plus a portion of another purchase acquired at a different unit cost, use a separate line for each purchase. If units are in inventory at two different costs, enter the OLDEST units first.

3. Determine the cost of the inventory on December 31 by the weighted average cost method.

4. would be preferred for income tax purposes in periods of rising prices.

Listed below are test grades for certain test.

27, 67, 85, 38, 92, 99, 87, 40, 56, 78, 88, 93, 97, 70, 66,

88, 45, 75, 90, 82, 65, 73, 85, 72, 65, 68, 90, 44, 56, 79 Given that the population mean is 72, and the population standard deviation is 19.

(1) Use the 68 − 95 − 99.7 rule to estimate the percentages of observations that lie with one, two, and three standard deviations of the mean.

(2) Use the data to obtain the exact percentages of observations that lie within one, two, and three standard deviations of the mean.

(3) Is it appropriate to use the 68 − 95 − 99.7 rule in this situation? Why?

(4) Regardless of your conclusion at (3). Suppose the grades of a test follows a Normal distribution with mean 72 and

standard deviation 19.

(a) What percentile are you in if your grade is 85?

(b) If you want to be in the top 5%, what grade do you need?

The S&H Mercantile in Luther is the only game in town for a number of items and tries valiantly to use only the storage space needed to display items since there is no stock room in the back of the store. One popular item, a 16-ounce can of dehydrated water, takes up 20 square inches of shelf space. The shelf space available for this item measures five feet by four feet. The store manager would like to order a quantity that can fill the shelf space without stacking and without needing to store cans elsewhere in the store. The amount ordered should all be on display once the S&H runs out and ideally would arrive just as the last can is purchased.

A. Suppose the annual demand is 8,000 units and the cost per can is $3 with a holding cost of 10%. What is the required order cost per lot?

B. Drought conditions spike demand during the summer to an annualized rate of 27,000 cans per year and the price rises to $12 per can with a holding cost of 20%. What is the required order cost per lot?

Statistics exercise

One-way BG ANOVA

    Suppose you would like to know if political party affiliation (democrat, republican, libertarian) has an effect on how people feel about the war in Afghanistan. You ask people to rate on a scale from 1-100 how much they support the war effort. Use the data below to see if the groups differed.

1. State the hypotheses

2. Select an alpha level and one- or two-tailed

3. Select and compute the appropriate statistic.

4. Report your findings in APA style

5. Accept or reject the null and draw an inference if one is warranted.

Consider the following information for a T-shirt manufacturing firm that can sell as many T-shirts as it wants for $10 per shirt.

a) Fill in the missing parts of the above table.

b) Verify that MRPl can be calculated in two ways: by change in TR and MPl times product price. If this firm must pay a rate of $285 per day, how many workers would be hired? Briefly explain.

c) Determine the highest wage rate necessary to hire 8 workers. Explain your answer.

d) Suppose the firm adopts a new technology that doubles output at each level of employment and that the price of shirts stays the same. Assume the wage rate is $285 per day. What would be the effect on the new technology on employment? Explain.
