Problem 4: House Prices

Use the “Fairfax City Home Sales” dataset for parts of this problem.

a) Use StatCrunch to construct an appropriately titled and labeled relative frequency histogram of Fairfax home closing prices stored in the “Price” variable. Copy your histogram into your document.

b) What is the shape of this distribution? Answer this question in one complete sentence.

c) Assuming the population has a similar shape as the sample with population mean $510,000 and population standard deviation $145,000; calculate the probability that in a random sample of size 10, the mean of the sample will be greater than $600,000. You may assume a random sample was taken and the sample came from a big population. However, be sure to check the central limit theorem condition of a large sample size before completing this problem using one complete sentence. If this condition is not met, you cannot complete the problem.

d) Assuming the population has a similar shape as the sample with population mean $510,000 and population standard deviation $145,000; calculate the probability that in a random sample of size 36, the mean of the sample will be greater than $600,000. You may assume a random sample was taken and the sample came from a big population. However, be sure to check the central limit theorem condition of a large sample size before completing this problem using one complete sentence. If this condition is not met, you cannot complete the problem.

DNA replication requires many enzymes to accomplish the process successfully. This results in a replication process that is known to be bi-directional, semi-conservative and semi-discontinuous. You discover a new prokaryotic organism that lacks the gene coding for an RNA polymerase I enzyme, and therefore this enzyme is not made in this species. Additionally, the DNA polymerase III enzyme from this organism lacks any 3’ to 5’ nuclease activity but has 5’ to 3’ nuclease activity. Based on what you know about DNA replication and the functions of DNA polymerase I and DNA polymerase III, discuss the effect of these changes on DNA replication in this organism. Please explain your answer in full.

Given an original message, determine the cipher that will produce the encoded string that comes earliest alphabetically. Return this encoded string. In the example below, the second cipher produces the alphabetically earliest encoded string ("abccd").

For example, if John's message is "hello" and his cipher maps 'h' to 'd', 'e' to 'i', 'l' to 'p' and 'o' to 'y', the encoded message will be "dippy". If the cipher maps 'h' to 'a', 'e' to 'b', 'l' to 'c' and 'o' to 'd', then the encoded message will be "abccd".

My code (bolded code is part of the question and cannot be changed):

string encrypt(string message){

// you write code here

string unEncryp;

for(int i = 0; i < message.length()){

char temp = message[i];

switch(temp){

default:

break;

}

}

return unEncryp;

Make C/4 capacitors by combining four capacitors in parallel; then combine three of these in series. Select which numbers of 1-6 would work for an equivalent capacitance of 3C/4

Come-Clean Corporation produces a variety of cleaning compounds and solutions for both industrial and household use. While most of its products are processed independently, a few are related, such as the company’s Grit 337 and its Sparkle silver polish.

Grit 337 is a coarse cleaning powder with many industrial uses. It costs $1.60 a pound to make, and it has a selling price of $7.00 a pound. A small portion of the annual production of Grit 337 is retained in the factory for further processing. It is combined with several other ingredients to form a paste that is marketed as Sparkle silver polish. The silver polish sells for $5.00 per jar.

This further processing requires one-fourth pound of Grit 337 per jar of silver polish. The additional direct costs involved in the processing of a jar of silver polish are:

Overhead costs associated with processing the silver polish are:

The production supervisor has no duties other than to oversee production of the silver polish. The mixing equipment is special-purpose equipment acquired specifically to produce the silver polish. Its resale value is negligible and it does not wear out through use.

Direct labor is a variable cost at Come-Clean Corporation.

Advertising costs for the silver polish total $2,500 per month. Variable selling costs associated with the silver polish are 5% of sales.

Due to a recent decline in the demand for silver polish, the company is wondering whether its continued production is advisable. The sales manager feels that it would be more profitable to sell all of the Grit 337 as a cleaning powder.

Required:

1. What is the incremental contribution margin per jar from further processing of Grit 337 into silver polish? (Do not round intermediate calculations. Round your answer to 2 decimal places.)

2. What is the minimum number of jars of silver polish that must be sold each month to justify the continued processing of Grit 337 into silver polish? (Round your intermediate calculations to 2 decimal places.)

Number of jars?

   1. Lower level managers are trained for increased responsibilities
   2. Managers are motivated to improve productivity
   3. Upper-level managers are able to concentrate on important decisions
   4. All of these are advantages of decentralization

2. When comparing EOQ and JIT inventory systems, which of the following statements is false?
   1. The EOQ system assumes a variable order quantity
   2. The EOQ system focuses on acquisition and holding costs
   3. JIT argues that inventory investments should be minimized
   4. The EOQ approach takes the viewpoint that some inventory is necessary
   5. JIT argues that safety stocks are unnecessary

3. Which of the following statements regarding responsibility accounting is not correct?
   1. It is most effective in a centralized business structure where senior managers exert control over various segments of a company’s operations
   2. It calls for the preparation of responsibility reports listing the budgeted and actual revenue and/or expense items over which the manager has control
   3. It requires top management to focus on long-term planning for the entire company and delegates the authority for implementing that plan to lower levels of management
   4. It calls for the preparation of report containing detailed information regarding the performance of a responsibility center

4. A factory that makes a part has no idle capacity. The factory’s opportunity cost of making this part is equal to?
