2. Consider the following sample of exam scores, arranged in increasing order. DO IT BY HAND AND SHOW WORK. NO WORK NO CREDIT. MAKE SURE YOU USE THE FORMULAS IN CLASS NOTES TO FIND LOCATION FOR PERCENTILES/QUARTILES. THE TEXTBOOK USES A DIFFERENT APPROACH AND RESULTS WILL BE DIFFERENT!

   28 57 58 64 69 74 79 80 83 85 85 87 87 89 89 90 92 93 94 94 95 96 96 97 97 97 97 98 100 100

   (Hint: the sample mean of these exam scores is 85)

1. Determine the interquartile range (IQR).

2. Obtain the five number summary.

3. Identify potential outliers if any.

4. Construct and interpret a boxplot or if appropriate, a modified boxplot.

4. Using the data in question 3 above, use Excel to

1. Determine the frequency distribution of exam scores. Use cutpoint grouping with

   25 as the first cutpoint and classes of equal width 5.

2. Determine the relative frequency distribution of exam scores

3. Find the following descriptive statistics of the exam scores using excel functions:

   Sample size (count), Mean, Variance, Standard Deviation, Minimum, Maximum, Range, Summation of observations in sample (sum), Mode, Median, Lower quartile-Q1, Middle quartile-Q2 (same as median), upper quartile-Q3 and Inter- quartile Range (IQR).

Please explain the solution to this problem to me conceptually as well as mathematically. I'd like to fully understand the transactions and the logic behind them. Thank you.

In year 1, Rim Corporation purchases 1,000 shares of treasury stock for $10 per share. In year 2, Rim reissues 100 shares of treasury stock for $12 per share. In year 3, Rim reissues 500 shares of its treasury stock for $9 per share. The journal entry to record the reissuance of treasury stock in year 3 will include which of the following entries?

Select all that may apply.

Credit paid-in-capital treasury shares for $500

Debit paid-in-capital treasury shares for $500

Debit paid-in-capital treasury shares for $200

Debit retained earnings for $300

Here is the solution:

First off, what are the relationships between treasury stock, retained earnings, and paid-in-capital treasury?

Secondly, how was the paid-in-capital and retained earnings journal entries calculated? What is the logic behind it?

Please explain it in a simple way.

Thanks!

Mark worked as route manager for United Trucks Pty Ltd in Queensland from 2003-17. A term of his contract was that if he should leave the company, he could not engage in the trucking industry in Queensland for five years. In 2018 he registered a company called Sunshine Trucks Pty Ltd. Mark owns 99% of the shares in the company. The other 1% is owned by his brother, Greg, whom he elected as sole director and CEO. Sunshine Trucks operates from Townsville and carries goods all over Queensland. Greg also signs a contract on behalf of the company, taking out a loan of $ 2 million from Grasping Bank in 2018 as start-up capital. The company did well during 2018, 2019 and the first half of 2020, but in July 2020 was not able to repay a loan instalment of $ 100 000 owing to Grasping Bank Ltd. Mark comes to you for advice after receiving two letters: One from United Trucks Pty Ltd requiring Sunshine Trucks Ltd to cease operating in Queensland, the other from Grasping Bank Ltd threatening to sue him for $ 100 000. Advise him, citing all relevant legal authority. Please note that you should assume that the restraint of trade clause in the contract that Mark had with United Trucks is valid under the law of contract. You should therefore not discuss that issue.

Advice Mark using ILAC.

For the scenarios answer the following:

a. State the independent (or quasi-independent) variable

b. State the dependent variable

c. Should the alternative hypothesis be one-tailed or two-tailed? Explain why.

d. State the null hypothesis

e. State the appropriate alternative hypothesis.

Scenarios1)  A researcher is interested in determining if there is a difference in the amount of time college students spend texting during class depending on where they sit in a classroom. He video tapes three different classrooms on campus and records the amount of time students in the front (first two rows), students in the middle (middle two rows) and students in the back (last two rows) of the classroom spend texting during the 45-minute lecture.

Scenario2) Ms. Nosienelly believes that adults will make more voice calls on their cell phone in public than adolescents will. To test her idea she asks a group of 100 fifteen-year-olds and a group of 100 forty-five-year-olds how many times a day they make a voice call on their cell phone while they are in public.

Scenario3) A university professor wanted to know if the way students were tested made a difference in their grades. One class took all their exams on a computer while a second class took all their exams on paper. The exact same exams were used for both groups. The grades on the exams were compared to see which group performed better

Describe the boundary lines for two- variable inequalities. Why are the boundary lines for two- variable inequalities with greater than and less represented by dotted lines? Provide examples.
First, define a boundary line and tell where it comes from. Then, describe what the boundary line can tell us about solutions to an inequality. You can also talk about how to know what part of a graph to shade. Finally , talk about the cases where we use each type of boundary line. ( solid and dotted/ dashed).
Real - life Relationship: If you have 100 $ available to buy party favors ( 3$ per bunch of balloons and 4 $ per bag of candy) than you can solve an inequality to find the possibilities . If x = # of bunches of balloons and y= number of bags of candy then we want to solve: 3x+ 4y<=100.
Some possible solutions are: no bunches of balloons and 25 bags of candy,20 bunches of balloons and 10 bags of candy. There are other possibilities!
Challenge: Imagine we have two boundary lines: one solid and one dashed. If they are not parallel is the point where they meet included in the solution? Why or why not?
If you are not sure, try an example, such as y < x + 1 and y < = 2x-4. Graph both boundary lines and find the point of intersection. Then , see if the coordinates satisfy both inequalities.

In Pennsylvania, 6,165,478 people voted in the election. Trump received 48.18% of the vote and Clinton recieved 47.46%. This doesn't add up to 100% because other candidates received votes. All together these other candidates received 100% - 48.18% - 47.46% = 4.36% of the vote.

Suppose we could select one person at random from the 6+ million voters in PA (note: PA is the common abbreviation for Pennsylvania). We are interested in the chance that we'd choose a Trump, Clinton, or Other voter.

Below is a probability table for the choice:

Suppose we take a simple random sample of ?=1500 n = 1500 voters from the 6+ million voters in PA. What is the expected number of Trump voters? What is the expected number of Clinton voters? To answer these questions, let ?1 T 1 be 1 if the first voter chosen for the sample voted for Trump and 0 if they voted for Clinton or another candidate. Let ?2 T 2 be 1 if the second voter chosen for the sample voted for Trump and 0 if they voted for Clinton or another candidate, and so on. Let's start with some very basic questions. Find: ?(?1000=1) P ( T 1000 = 1 ) ?(?1000=0) P ( T 1000 = 0 ) ?(?17) E ( T 17 )

JAVA - Programming Exercise 10-5.

The developers of a free online game named Sugar Smash have asked you to develop a class named SugarSmashPlayer that holds data about a single player. The class contains the following fields: idNumber - the player’s ID number (of type int) name - the player's screen name (of type String) scores - an array of integers that stores the highest score achieved in each of 10 game levels Include get and set methods for each field. The get method for scores should require the game level to retrieve the score for. The set method for scores should require two parameters—one that represents the score achieved and one that represents the game level to be retrieved or assigned. Display an error message if the user attempts to assign or retrieve a score from a level that is out of range for the array of scores. Additionally, no level except the first one should be set unless the user has earned at least 100 points at each previous level. If a user tries to set a score for a level that is not yet available, issue an error message. Create a class named PremiumSugarSmashPlayer that descends from SugarSmashPlayer. This class is instantiated when a user pays $2.99 to have access to 40 additional levels of play. As in the free version of the game, a user cannot set a score for a level unless the user has earned at least 100 points at all previous levels.

Determine the mean and standard deviation of your sample.

Find the 80%, 95%, and 99% confidence intervals. Make sure to list the margin of error for the 80%, 95%, and 99% confidence interval.

Create your own confidence interval (you cannot use 80%, 95%, and 99%) and make sure to show your work.

Make sure to list the margin of error.

What trend do you see takes place to the confidence interval as the confidence level rises?

Explain mathematically why that takes place.

Provide a sentence for each confidence interval created in part c) which explains what the confidence interval means in context of topic of your project. Explain how Part I of the project has helped you understand confidence intervals better? How did this project help you understand statistics better?

Write a C++ program that inputs a sequence of integers into a vector, computes the average, and then outputs the # of input values, the average, and the values themselves. There are 0 or more inputs values, followed by a negative value as the sentinel; the negative value is not stored and not counted. The following sample input:

10
20
0
99
-1

would produce the following output:

N: 4
Avg: 32.25
10
20
0
99
