As Economic Analyst for High Desert Bank, analyze the amounts of commercial, consumers, and real estate loans.

1. Construct two 95% confidence intervals for each sample.

• Apply the population standard deviation (σ) in the formula to form z-distribution since the population standard deviation is known.
• Apply the sample standard deviation (s) in the formula to form t-distribution assuming the population standard deviation is unknown.

In C++, I have 3 files (Main.cpp, Point.cpp, Point.h). When Compiled and run, it produces 2 errors, in Main.cpp "cannot convert from double to point" and in Point.cpp "name followed by :: must be a class or namespace name". How do you go about fixing these errors without editing Main.cpp? Thanks in advance.

What is the purpose of a planning and control system related to scheduling?

Andalus Furniture Company has two manufacturing plants, one at Aynor and another at Spartanburg. The cost in dollars of producing a kitchen chair at each of the two plants is given here. The cost of producing Q1 chairs at Aynor is: 25Q1+2.5Q12+100 and the cost of producing Q2 kitchen chairs at Spartanburg is: 75Q2+2.5Q22+150. Andalus needs to manufacture a total of 40 kitchen chairs to meet an order just received. How many chairs should be made at Aynor, and how many should be made at Spartanburg in order to minimize total production cost? If required, round your answers to the nearest whole number. Round intermediate calculations to two decimal places.

Contribution Margin, Break-Even Sales, Cost-Volume-Profit Chart, Margin of Safety, and Operating Leverage

Belmain Co. expects to maintain the same inventories at the end of 20Y7 as at the beginning of the year. The total of all production costs for the year is therefore assumed to be equal to the cost of goods sold. With this in mind, the various department heads were asked to submit estimates of the costs for their departments during the year. A summary report of these estimates is as follows:

It is expected that 6,480 units will be sold at a price of $360 a unit. Maximum sales within the relevant range are 8,000 units.

Required:

1. Prepare an estimated income statement for 20Y7.

2. What is the expected contribution margin ratio? Round to the nearest whole percent.
%

3. Determine the break-even sales in units and dollars.

4. Construct a cost-volume-profit chart on your own paper. What is the break-even sales?
$

5. What is the expected margin of safety in dollars and as a percentage of sales?

6. Determine the operating leverage. Round to one decimal place.

Bronner’s Christmas Store is one of the largest in America. Bronner’s currently has one store located in Frankenmuth, Michigan. Bronner’s has decided to open up a second store in Heidelberg, Germany. Reflecting on each chapter in our textbook, respond to each of the following questions as though you were hired to be a consultant to Bronner’s.

What are some of the import/export issues that Bronner's may face with the new location?

Using jGRASP, write a Java program named LastnameFirstname11.java, using your last name and your first name, that does the following:

• Defines a method called generateNums. This method will create an array of size x, fill it with random numbers between y and z, then return the array. When you call the method, you must specify the size of the array (x), the beginning of your random number range (y), and the ending of your random number range (z).
• Defines a method called avgNums. You will be able to pass a double array to this method. This method will add up all the numbers in the array. Then it will divide that sum by the size of the array to find the average of all the numbers. Return the average.
• Asks the user for input to determine the array size and what range of random numbers to generate.
• Calls the generateNums method 5 times to create arrays based on the user's input.
  • Store each of the returned arrays into a variable.
• Calls the avgNums method 5 times.
  • Store each of the returned arrays into a variable.
• Prints the results, displaying 4 digits after the decimal.

Please fllll this out thank you

Andre, a student preparing for his final exams, has an argument with his parents regarding the use of IPod during study hours. According to his parents, listening to music while studying affects cognitive performance and will pose serious impediments in Andre’s ability to focus. But Andre provides a counter-argument, as he believes that music acts as a stress buster. He says that it helps in the release of dopamine that relieves stress and relaxes the mind. Do you agree with Andre? Provide justification for your answer in about 200-300 words.
