Which statement about sample size in qualitative research is true?

In C++, develop a menu program which reads in data from 4 different input files - appetizers, entrees, desserts, and drinks. Then, record the item information ordered by the customer for each item selected. When finished, display all items ordered to the screen with the subtotal, tax (10% for easy math), and the total. Be sure to get tip as well. Then, ensure enough payment was received before generating an output file receipt which can be printed off. Use functions to prevent redudant code.

• You are free to use arrays or vectors to store program data. Your choice!
• The input files can have different numbers of items available. Example: You have may have 5 appetizers, 10 entrees, 8 drinks and 4 desserts. The numbers are up to you. But, the program should be able to handle input files with "unknown numbers" of items for sale.
• Make the interface and output look nice! Software is something that you want to sell to others. If it looks bad, no one will buy it. Think about the last app you downloaded that didn't look good when you used it. Do you still have it on your phone? Probably not.
• Your program must not have redundant code! Use functions and/or generic functions where possible to remove all redundant code in your program.

(a) It is commonly accepted that there are gains from adding securities to an
investment portfolio. Explain what is meant by this statement. (Your answer
should include a discussion and example regarding systematic and
non‐systematic risk as well as an indication of the optimal number of assets to be
included within a portfolio in theory and in practice.)

5. A non-governmental organization needs a program to calculate the amount of financial assistance for needy families. The formula is as follows:5 pts

• If the annual household income is between $30,000 and $39,999 and the household has at least three children, the amount is $1000 per child.
• If the annual household income is between $20,000 and $29,999 and the household has at least two children, the amount is $1500 per child.
• If the annual household income is less than $20,000, the amount is $2000 per child.

(Note: anything outside these conditions, there is NO financial assistance)

Implement a function for this computation. Write a program that asks for the household income and number of children for each applicant, printing the amount returned by your function. Use a -1 as a sentinel value for the input.

DefcomputeAssistance (income, children)

1. Your code with comments
2. A screenshot of the execution

Test Cases:

            Household income = $35,000             No. of children = 4 (should return $1000/child)

            Household income = $25,000             No. of children = 3 (should return $1500/child)

            Household income = $18,000             No. of children = 2 (should return $2000/child)

            Household income = $40,000             No. of children = 1 (should return “No assistance”)

The following selected transactions relate to investment activities of Ornamental Insulation Corporation during 2018. The company buys debt securities, not intending to profit from short-term differences in price and not necessarily to hold debt securities to maturity, but to have them available for sale when circumstances warrant. Ornamental’s fiscal year ends on December 31. No investments were held by Ornamental on December 31, 2017.

(Hint: Interest must be accrued.)

Required:
1. Prepare the appropriate journal entry for each transaction or event during 2018, as well as any adjusting entries necessary at year end. For any sales, prepare entries to update the fair-value adjustment, record any reclassification adjustment, and record the sale.
2. Indicate any amounts that Ornamental Insulation would report in its 2018 income statement, 2018 statement of comprehensive income, and 12/31/2018 balance sheet as a result of these investments

Indicate any amounts that Ornamental Insulation would report in its 2018 income statement, 2018 statement of comprehensive income, and 12/31/2018 balance sheet as a result of these investments. (Amounts to be deducted should be indicated with a minus sign.)

C++ - Checks the relevance of a data structure in terms of following the interface specification for an ADT that represents a linear data structure:

Depending on the ADT of linear data structure, you must create the operations CRUD (Create, Read (search), Update, Delete) elements in the data structure. Some operations do not apply for certain data structures

Create:

Description: Insert an element in the data structure (create) according to the access policy of the structure

Input:Data structure and element to insert
Output: Valid data structure showing the insertion of the element
Precondition: A valid structure
Postcondition: Modified structure

Read:

Description: Read (search, obtain, etc.) an element within the data structure (read) according to the access policy of the structure
Input: The data structure and additional information about the item to retrieve (depending on the data structure)
Output: Element meeting the input or error criteria (there is no element with those characteristics)
Precondition: Valid data structure
Postcondition: Nothing

Update:

Description
Update an element within the data structure (update) according to the specific data structure

Input: Data structure, element to update, values ​​to modify
Output: Data structure duly updated
Precondition: A valid data structure
Postcondition: Data structure duly updated

Delete:

Description
Delete (remove) an element within the data structure (del) according to the specific data structure

Input: A data structure and criteria that determine the element to delete
Output: Updated data structure
Precondition: A valid data structure
Postcondition: Data structure duly updated

A survey is designed to estimate the proportion of sports utility vehicles (SUVs) being driven in the state of California. A random sample of 500 registrations are selected from a Department of Motor Vehicles database, and 26 are classified as SUVs.

(a)Use a 95% confidence interval to estimate the proportion of sports utility vehicles in California. (Round your answers to three decimal places

(b) How can you estimate the proportion of sports utility vehicles in California with a higher degree of accuracy? (HINT: There are two answers. Select all that apply.)

increase the sample size n increase z_α/2 by decreasing the confidence coefficient conduct a non-random sample increase z_α/2 by increasing the confidence coefficient decrease z_α/2 by increasing the confidence coefficient decrease the sample size n decrease z_α/2 by decreasing the confidence coefficient

Use adventure works 2014 database to solve the following questions in SQL management studio.

1. Create a stored procedure that will receive parameters (all non-nullable fields should be supplied except the primary key which should be auto created still) to add a customer, single email, and single phone. The procedure should run it's code in a transaction and if any part of the add fails then the transaction should rollback.

2. Provide this query from previous assignments written with an isolation level that won't see your procedure transaction above until it's complete. Using joins List the orders customer name, order status, date ordered, count of items on the order, and average quantity ordered where the count of items on the order is greater than 300.

the data tables for second question are: sales.customer, sales.salesOrderHeader, Person.Person, sales.salesOrderDetail
