The Department of Statistics at Great Ivy University offers Stat 101 – Introductory Statistics with the use of a calculator. The Department wants to see if students in Stat 101 will benefit more by adding a new software package to Stat 101 versus keep using only the calculator. Five of 10 sections chosen at random will be required to rent the software, the other five will not. Re same
(a) Is this a one-tailed or a two-tailed test? Explain.
(b) State the null and alternative hypotheses. (Remember: The null hypothesis is one of no effect, i.e. no difference in exam grades.)
(c) In this context, what would a Type I error be? What are the consequences?
(d) In this context, what would a Type II error be? What are the consequences?
(e) Which error type is more serious? Explain

Two nonprofits are interested in sharing fundraising lists and campaigns as they think their donors share common interests. Implicit in that assumption is they are related variables. You collect data below for thirteen donors and want to test if there is a relationship between donations (in dollars) (data is collected below)
Charity A:
50 70 60 30 30 60 100 20 40 60 30 80 60
Charity B:
60 45 65 50 30 30 90 40 50 70 40 55 40
a.) State the null both formally and in lay terms
b) Calculate r and the regression line (y = a + bx) and
reject/accept at a=.05. What is the regression line please state
it?
c) Explain your findings in lay terms using r-square, r, b as appropriate
d) Calculate a 95% confidence interval for the slope if it is necessary if it is not please explain. Provide the formal interval and explain in layterms.

Please include all steps. Thanks
An urn model is known in the field of probability and statistics as a useful representation of a
probabilistic problem using coloured balls in an urn. There are many different variations of an
urn model. For this problem, consider the following case:
• There is an urn with 1 red ball and 1 blue ball.
• Every time a ball is drawn (at random) from the urn, it is placed back in the urn along with
2 more balls of the same colour as the ball that was drawn, and 1 more ball of the other
colour.
Denote the random variable Xi to be the number of red balls after the i-th drawn ball (for
i = 1, 2 . . .). Note that Xi is the random variable for the number of red balls in the urn including
the three new balls added after the i-th draw.
(a) Find the probability mass function (pmf) of X2.
(b) What is the probability that the first ball drawn was red, given that there are at least 5 red
balls after the third ball is drawn.
(c) Compute E(X3) and Var(X3).

Submit a paper which is 2-3 pages in length (no more than
3-pages), In this paper, in addition to presenting the
computed answers, please also discuss how you arrived at each
answer the accounting problem asks. The accounting problem presents
a company’s balance sheet, income statement, and statement of cash
flows for a theoretical company, Polly’s Pet Products. Each of
these statements has blank lines. Determine the values that would
be appropriate for each blank line. Provide a narrative of how you
arrived at each value. Include in this narrative an explanation
of:
1) the financial statement being completed;
2) the account being valued;
3) its relationship to the other financial data.
For example, if the accounts payable (AP) line was missing, describe what a balance sheet is and explain that you can derive the AP value based on knowing all the other values of the current liabilities section. Then explain what an account liability is, as well as why it would belong in the current liabilities section of the balance sheet. Finally, analyze, evaluate, and develop a conclusion about the company’s performance based on the completed statements.To complete this assignment, refer to the income statement, balance sheet, and statement of cash flows of Polly’s Pet Products.
Please Note:
Superior papers will mention and explain the following elements when responding to the assignment question:
Provide correct balances for the blank financial account lines.
Define the financial statement being completed.
Discuss how the values were determined.
Define and explain each account line that was completed.
Analyze, evaluate, and develop conclusions about the company’s performance based on the financial information.

In what ways did the Cold War reshape global politics?
Topic Sentence/Thesis Statement: Your first sentence should directly answer the question in the assignment. It should be clear and direct, and provide an argument. If you write a sentence that is too general, then you will not be able to organize your answer and to provide details.
First Criterion: In this section, you will provide and analyze evidence that supports the first part of your Thesis Statement. Remember to use evidence from your textbook and primary sources. After presenting your information, make sure you cite your information.
Second Criterion: Like above, provide and analyze your evidence. Make sure that you transition between the different sections of your argument.
Third Criterion
Conclusion: Here, you want to summarize your ideas without repetition. The best way to do so is to rephrase your thesis statement.
