Part 1: Summarize the current state of the economy. o Do this using economic data and reports. Be sure to interpret the data you present. o Be sure to use economic theory and models to help explain what is going on at this moment.

 Part 2: Discuss what you think the state of the economy will look like at the time of your last graduation (with your highest planned degree) and what that will mean for your job prospects and your income earning potential. o Do this by referring to published economic forecasts, or by making your own economic forecast. o Be sure to use economic theory and models to help explain why you think economic conditions will be as you predict. o Be sure to think about how your specific degree and profession will fit into the future labor market

 Part 3: Discuss one major financial goal you wish to accomplish in the next 10 years, set up a simple financial plan to reach that goal, then discuss how the performance of the economy and economic policies could affect your ability to reach that goal. o Start by stating your personal financial goal and briefly summarizing your financial plan.  Then discuss what assumptions you are making about the economy and your financesin your financial plan  Then use economic theory and models to explain what events/changes could accelerate or derail the pursue of your goal o Think about the probability of a recession, probability of unemployment in your profession, average return on investments, potential wage growth, inflation, etc… in the next 10 years.

Paper Requirements:  4 pages (typed double spaced)  Whenever you refer to a vocabulary term / concept / theory / principle from class you should bold and underline the text. o for example: "The economy isin a recessionwith the unemployment rate dramatically above the natural unemployment rate."  4 outside /verifiable references (APA or MLA style) with in-text citations and a full works cited section. o These references must be 4 different, outside sources from verifiable sources; no blogs, and no wikis. Your textbook does not count as one of your required citations.

It is about C++linked list code. my assignment is making 1 function, in below circumstance,(some functions are suggested for easier procedure of making function.)

void pop_Stack (struct linked_list* list, int number) //*This is the function to make and below is the explanation that should be written in given code.

This function removes some nodes in stack manner; the tail of the list will be removed, repeatedly. The parameter (variable 'number') means the number of nodes that will be removed. When parameter is bigger than 1, popping a node with n times, you do not remove node at one go. If there is only one node in the list, please make sure it frees (de-allocates) both the node and the list. If the list is not a stack type(list->type_of_list!=1), print the error message “Function pop_Stack: The list type is not a stack” and exit the function. If the 'number' parameter is less than 1 or more than the number of nodes in the stack, respectively print the error message “Function popStack: The number of nodes which will be removed is more than 1” and “Function popStack: The number of nodes which will be removed is more than that in the stack”, then exit the function. The removed nodes should be freed.

Given code is written below,(There is a function to fill in last moment in this code)

1. As a special promotion for its 12-ounce cans of cold coffee, a coffee drink company printed a message on the bottom of each can. Some of the bottoms read, "Better luck next time!" whereas others read, "You won!" The company advertised the promotion with the slogan "One in five wins a prize!" Suppose the company is telling the truth and that every 12-ounce can of coffee has a one-in-five chance of being a winner. Six friends each buy one 12-ounce can of coffee at a local convenience store. Let X equal the number of friends who win a prize.

Part A: Explain why X is a binomial random variable. (3 points)

Part B: Find the mean and standard deviation of X. Interpret each value in context. (4 points)

Part C: The store clerk is surprised when two of the friends win a prize. Is this group of friends just lucky, or is the company's one-in-five claim inaccurate? Compute P(X ≥ 2) and use the result to justify your answer.

2. The army reports that the distribution of waist sizes among female soldiers is approximately normal, with a mean of 28.4 inches and a standard deviation of 1.2 inches.

Part A: A female soldier whose waist is 26.1 inches is at what percentile? Mathematically explain your reasoning and justify your work. (5 points)

Part B: The army uniform supplier regularly stocks uniform pants between sizes 24 and 32. Anyone with a waist circumference outside that interval requires a customized order. Describe what this interval looks like if displayed visually. What percent of female soldiers requires custom uniform pants? Show your work and mathematically justify your reasoning.

NOTE :- Please find the probabilities as functions of cost

A service facility charges a $20 fixed fee plus $25 per hour of service up to 6 hours, and no additional fee is charged for a service visit exceeding 6 hours. Suppose that the service time τ again ranges from 0 to 10 hours, but now the probability density is twice as large during the middle 6 hours [2, 8] than during the outer 4 hours [0, 2] and [8, 10]. (Note as before that τ is a continuous random variable.) Let X represent the cost of service in the facility.

We would like to set up the probability density function (PDF) and the cumulative distribution function (CDF), then use them to analyze service fees.

Design Specifications

  1. Sketch the probability density as a function of time. Be quantitative, and pay attention to units. Compute the probability that the service is greater than 6 hours. Then, sketch the probability density as a function of cost. Again, be quantitative and pay attention to units

  2. Use the probability density function to set up the cumulative probability, also as a function of X.
