(4) An urn contains 7 red marbles labeled {1,2,3,4,5,6,7} and 5 green marbles labeled {1,2,3,4,5}.Four marbles are pulled out at once (i.e. with no particular order). What is the probability that ...

(a) ... all four marbles are red?

(b) ... more of the marbles are green than red?

(c) ... both red and green marbles are present?

(d) ... two of the marbles chosen are both labeled "5"?

We are given 3 urns as follows: Urn A contains 3 red and 5 white marbles, Urn B contains 2 red and one white marble, Urn C contains 2 red and 3 white marbles. Construct the probability tree. Suppose that a urn is randomly selected and a marble is drawn from the selected urn. If the marble is red what is the probability that it came from urn A?

Fill out the answer sheet for each of the hypothesis tests below, using a 5% level of significance. Use 4 decimal places, unless the p-value is really small (less than 0.0001), in which case use at least 2 significant figures This means 2 non-zero numbers somewhere after the decimal point). Axis of graphs should be drawn with a ruler or done on a computer.

Suppose that students own an average of 4 pairs of jeans. 8 people from your class were surveyed to determine if the average for students at De Anza College is higher than 4.

DATA TO USE: 2,2,3,4,6,6,8,9

a. Give the null and alternative hypotheses: Ho: _______________ Ha: ___________________

b. In words, CLEARLY state what your random variable X or P' represents.

c. State the distribution to use for the test. If t, include the degrees of freedom. If normal, include the mean and standard deviation.

d. p-value = ______________

e. In 1 – 2 complete sentences, explain what the p-value means for this problem.

f. Use the previous information to draw a graph of this situation. CLEARLY, label and scale the horizontal axis and shade the region(s) corresponding to the p-value. The values of your sample statistic and the hypothesized value of the population parameter should be on the axis.

g. Indicate the correct decision (“reject the null hypothesis” or “do not reject the null hypothesis”) and write an appropriate conclusion, using COMPLETE SENTENCES.

Decision:

Conclusion:

h. Construct a 95% Confidence Interval for the true mean or proportion. Include a sketch of the graph of the

situation. Label the point estimate and the lower and upper bounds of the Confidence Interval.

Confidence Interval: ( ___________________ , ___________________ )

i. Interpret the confidence interval in a complete sentence.

The charts show results of studies on four-year colleges in the United States. You want to portray your college in a positive light for an advertising campaign designed to attract high school students. You decide to use hypothesis tests to show that your college is better than the average in certain aspects. EXERCISES

1. What Would You Test? What claims could you test if you wanted to convince a student to come to your college? Suppose the student you are trying to convince is mainly concerned with (a) affordability, (b) having a good experience, and (c) graduating and starting a career. List one claim for each case. State the null and alternative hypotheses for each claim.

2. Choosing a Random Sample Classmates suggest conducting the following sampling techniques to test various claims. Determine whether the sample will be random. If not, suggest an alternative. (a) Survey all the students you have class with and ask about the average time they spend daily on different activities. (b) Randomly select former students from a list of recent graduates and ask whether they are employed. (c) Randomly select students from a directory, ask how much debt money they borrowed to pay for college this year, and multiply by four.

3. Supporting a Claim You want your test to support a positive claim about your college, not just fail to reject one. Should you state your claim so that the null hypothesis contains the claim or the alternate hypothesis contains the claim? Explain.

4. Testing a Claim You want to claim that students at your college graduate with an average debt of less than $25,000. A random sample of 40 recent graduates has a mean amount borrowed of $23,475 and a standard deviation of $8000. At a = 0.05, is there enough evidence to support your claim?

5. Testing a Claim You want to claim that your college has a freshmen retention rate of at least 80%. You take a random sample of 60 of last year’s freshmen and find that 54 of them still attend your college. At a = 0.05, is there enough evidence to reject your claim?

6. Conclusion Test one of the claims you listed in Exercise 1 and interpret the results. Discuss any limits of your sampling process.

From what you've learnt so far, write a report on the agile development methodology from the point of view of a programmer trying to argue the case for management of Academic City College to adopt a specific methodology for internal system development and contracted (procured) system development. You can assume the organisation has no experience in agile development processes at all so you will need to provide detailed arguments (this is not true but for the purposes of the assignment you should assume it is true).

Your report should be structured as follows:

1. An overview of Agile processes

2. An explanation of your specific proposed framework

3. Arguments for and against the adoption of your proposed framework. You will need to reference authoritative sources to convince your management

4. Clearly identify what sorts of projects would benefit and what sorts of projects will not benefit . This can be part of your point 3 arguments.

5. An explanation of two aspects of Agile methodologies (XP, SCRUM or other processes) that could be adopted across the organisation, even if some systems were not appropriate for your proposed framework. Explain why this is a good idea.

The report should not be more than 1500 words. You will not be penalised for going over the limit but it may indicate you have too much detail or your writing is not precise. Feel free to use the above items as major headings in your report/essay, a bit more concise of course. You should add a brief Executive Summary and a brief Conclusion.

Suppose Canada’s aggregate production function is given by the following:
Y = (K*1^3)(N*2^3)


Variables are defined as they were in class. Suppose the savings rate in Canada is 33.33% (s = 1 3) and the depreciation rate is 15% (δ = 0.15). Assume that Canada is not currently experiencing any technological change.
a) Calculate the steady-state level of capital per worker and output per worker in Canada’s economy.

b) Determine the annual growth rate of output per worker in Canada.

The government wants to grow the economy by encouraging more savings. Suppose they successfully persuade Canadians to increase the savings rate to 40% (s = 0.4).
c) Graph the resulting annual growth rate of GDP per worker for the following 100 years. What is the new steady state level of GDP per capita? Has increased savings led to a large growth in the economy?

d) Calculate the golden-rule savings rate for this economy.

e) Explain what your result from part d) say about the desirability of Canada’s increased savings policy.

Monetary and fiscal policy are seen as appropriate tools to try to steer the macroeconomy. What are the current settings of these tools? Who makes the decisions to change one of these tools? Are the decisions based on democratically elected officials actions or appointees? What are the advantages and drawbacks of elected officials vs. Appointees?? Explain in detail.

- Where is the smartness incorporated in the Internet?

- What is the Internet end-to-end principal?
