You are watching TV with a friend of yours, who was not lucky enough to go to business school and take a course on marketing research. On TV, a journalist explains that, according to the latest poll, “pollsters are confident at 95% that 64% (+ or – 3%) of the French voters would vote for Mr. Biden and 36% (+ or – 3%) for Mr. Trump, if the presidential elections were held today”. The journalist adds that those results are based on a poll conducted among 1,054 registered voters.

Your friend tells you that “It’s ridiculous to interview only 1,054 people and believe you can generalize your findings to a population of millions of people… You have to interview ALL the U.S. registered voters if you want your findings to be accurate! A census is always better that a poll based on a sample!” Based on what you have learned in this course,

(1) explain to your poor friend why she is not right.

Also, (2) tell her what pollsters mean by “margin of error” and “confidence interval”.

Subject: Seminar in Leadership and Influence.

Q11

Part 1) Think about all the leaders you have ever had in work and/or school environment. Include supervisors, project managers, internship managers, professors, mentors, or any others who were in positions of authority. Pick one leader with whom you had no problems in the working relationship and pick one leader with whom you had some or severe problems. Compare these two leaders’ leadership styles and behaviors and describe why you have had a smooth relationship with the good one and why you may have had problems with the bad one. You may need to reflect upon your own values, working styles, and expectations when you describe your two contrasting followership experiences. After the discussion of the two brief examples

Part 2) show me your top 3 takeaways about leadership development based on your own leadership experience and our class discussions.

"Today’s Attacks and Defenses at the beginning of this chapter illustrated how a security researcher could manipulate a help desk support technician into compromising security. If you were to create your own social engineering attack, what would it be? Using your place of employment or school, first determine exactly what your goal would be in the attack, and then craft a detailed description of how you would carry out the attack using only social engineering to achieve your goal. You might want to search the Internet for examples of previously successful attacks that used social engineering. Why do you think your attack would be successful? Who would be involved? What would be the problems in achieving your goal? Why? Write a one-page paper on your research"
(Ciampa 93).

As instructed, write a one-page paper on your research. Make sure that your paper is double-spaced and has an introduction, conclusion and any appropriate citations and references.

The city of Belle collects property taxes for other local governments—Beau County and the Landis Independent School District (LISD). The city uses a Property Tax Collection Custodial Fund to account for its collection of property taxes for itself, Beau County, and LISD. Prepare journal entries to record the following transactions and events for Belle’s Custodial Fund during calendar year 2019.

1. During 2019, property taxes were levied for Belle ($2,000,000), Beau County ($1,000,000) and LISD ($3,000,000). Assume taxes collected by the Custodial Fund will be paid to Belle’s General Fund.

2. Property taxes in the amount of $4,500,000 are collected. The percentage collected for each entity is in the same proportion as the original levy.

3. The amount owed to the city of Belle, Beau County, and LISD is recognized. The city of Belle charges an administrative fee to Beau County ($20,000) and LISD ($60,000) to collect the taxes, which reduces the amount owed to Beau County and LISD.

4. The Custodial Fund distributes the amount owed to the three governments.

You want to create a study to examine the psychological factors affecting how teenagers in an impoverished urban area spend their time outside of school. For this assignment, you will design this study. Below is a list of each of the components on which you will be evaluated. You will be evaluated based on the following: Use of the scientific method. Discussion of which methods you used, why, and potential sources of error. Explanation of the relationship between the hypothesis vs. the null hypothesis; and connection to your study. Analysis of potential ethical issues, their importance in research, and how to address them. Discussion of potential issues regarding culture, gender, diversity, or the environment and how to address them. Explanation of which types of sources were used and how these choices may affect results. An overview of how you would present your findings and why they can be classified as being within the field of psychology. Please provide your answers in a 3- to 4-page Microsoft Word document Cite any sources in APA format.

3-) A heat exchanger with 1 body - 4 pipe passages and each pipe (100+ ??) (with a diameter of 2.6 cm each, 4 m long thin wall per pass) will be used to heat the air. Water enters the pipes with a mass flow of 8 kg / s at 350 K temperature, and air enters the body at a temperature of 15 C with a mass flow of 18 kg / s. The pollution factor of the sediment formed inside the pipe over time is 0.0026 m'K / W. Transport coefficients on the inner and outer surfaces of the pipes are estimated at 450 and 200 W / m'K, respectively. Using specific temperatures at 25 ° C for air and water (?? = school no. Last two digits, for example 0611002072; ?? = 72, ie 172 units), a-) the efficiency of the heat exchanger by drawing the shape of the problem, b-) Heat transfer rate ( kW), c-) Calculate the outlet temperatures (C) of the water and air and show the temperatures in the T_L diagram.

Prepare an income statement using Absorption Cost and other using Variable costs.

D's company produce donuts.

The variable cost of making each box of donuts is $ 0.40.
The Fixed Production Costs are $ 65,000.
Administrative and variable sales expenses are $ 0.20 per box.
The administrative and sales Fixed Costs are $ 55,000.

During 2018 the company produces 500,000 and sells 450,000 boxes of donuts to $ 1. The company has the capacity to produce 600,000 boxes of donuts. The company uses a calendar year and this is its first year of operations.

1. Prepare the Income Statement for full costs (absorption cost) and for variable costs. There is no tax rate.

2. A school wishes to raise funds for the graduating class. They extend an offer to buy 5,000 boxes per month for 10 months at $ 0.60. If the company accepts, this sale will not affect normal sales. The company must incur all variable costs, but not fixed costs. Determine if you accept the offer or reject it. Present your computations.

When you stick ice in a drink, AFAICT (the last physics I took was in high school) two things cool the drink:

• The ice, being cooler than the drink, gets heat transferred to it from the drink (Newton's law of cooling). (This continues after it melts, too.)
• The ice melts, and the cool liquid mixes with the drink, which makes the mixture feel cooler.

My first question is, to what extent does each of these cool the drink: which has a greater effect, and how much greater?

Secondly, how much of the cooling by the first method (heat transfer) is without melting the ice? That is, is there any significant amount of heat transfer to each speck of ice before it's melted, and how much does that cumulatively affect the drink's temperature?

I suppose all this will depend on a bunch of variables, like the shape and number of ice cubes and various temperatures and volumes. But any light that can be shed, let's say for "typical" situations, would be appreciated.
