Burping (also known as "belching" or "eructation") is one way the human body expels excess gas in your digestive system. It occurs when your stomach fills with air, which can be caused by swallowing food and liquids. Drinking carbonated beverages, such as soda, is known to increase burping because its bubbles have tiny amounts of carbon dioxide in them.

As an avid soda drinker and statistics student, you notice you tend to burp more after drinking root beer than you do after drinking cola. You decide to determine whether there is a difference between the number of burps while drinking a root beer and while drinking a cola. To determine this, you select 20 students at random from high school, have each drink both types of beverages, and record the number of burps. You randomize which beverage each participant drinks first by flipping a coin. Both beverages contain 12 fluid ounces. Here are the results:

Participant 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
Root beer 6 8 7 7 4 2 3 6 3 8 2 1 5 1 3 4 2 4 5 10
Cola 4 5 5 6 2 3 3 5 4 7 4 0 5 3 3 2 1 1 7 7

Part A: Based on these results, what should you report about the difference between the number of burps from drinking root beer and those from drinking cola? Give appropriate statistical evidence to support your response at the α = 0.05 significance level.

Part B: How much of a difference is there when an individual burps from drinking root beer than from drinking cola? Construct and interpret a 95% confidence interval.

Part C: Describe the conclusions about the difference between the mean number of burps that might be drawn from the interval. How do they relate to your conclusion in part A?

Please Please fulfill the requirements and error handling and make this in basic C++ construct Thank you!!

Objectives:

  • Perform C++ string object manipulation
  • Understand how to manipulate data using arrays
  • Handle input errors and invalid values
  • Design and create a well-structure program using C++ basic programming constructs

Description:

Write a menu-driven program that provides the following options:

  1. Show All
  2. Spend
  3. Search expenses containing this string
  4. Search expenses with greater than or equal to this amount
  5. Exit

It allows the user to select a menu option to display all expenses, add new entry, search for a substring and find the list of entries greater a given amount.

Requirements:

  1. The program must produce similar output as example below. The output should be formatted nicely as given.
  2. The program must use array of structs
  3. The program must not use global variables. In another words, it must use local variables and pass-by-value or pass-by-reference parameters.
  4. The program must define the maximum number of entries such as 100 and keeps track of the actual count of the current number of expenses entered by the user
  5. You should not use data file to save or read from. All operations should be done through the use of arrays and array indices.
  6. You must write at least 2 functions.

Required error handling:

The program MUST perform the following checks:

  1. Check for invalid amount (negative or 0 number)
  2. Description cannot be empty.
  3. Search is case-insensitive (ignore case, but the user may type in any case).

Harper, Inc. is incorporated in State 1 but also has offices in States 2, 3, and 4. All four states use the Uniform Division of Income for Tax Purposes Act (UDITPA) three-factor formula for determining the state apportionment percentage. Based on the following financial information, what percentages of Harper’s income should be apportioned to States 1 and 2? Round to the nearest whole percentage. Please show your calculations at how you arrived at your answer.

Question 1

price is an instance variable of a class. Inside that class there is a method public void change(int price).

From inside the method " change" how do we refer to the instance variable price and not the parameter price?

Answer:

Question 2

Create properly formatted script file (Initials_Final_pb_02.m) that will prompt the user to input a 1-D array of numbers (positive, negative, zero) and then use loop and conditional statement to find the number of all non-zero elements in this array and their products

Do NOT use the built-in commands such as sum, prod, length, size, … etc.

-        Use proper names for input and output variables.

Use the following 3 vectors to test your function and include the results as a commented text at the end of your script file. [3 -1 0 -4 2], [10 -15 20 -15 0], [1 0 -2 5 -2 3]

Format the output using fprintf similar to the following:
