Please solve the following questions attached: ignore the following*Econ 2500 Section D 3.0 – Fall 2016Assignment 2(Due Date: November 24, 2015)Question 1: Let X be a continuous random variable with probability density functionf(x) =cx 0 2|1 ≤ X ≤ 3).Question 2: Statistics Canada reported that 13% of Canadians are left-handed. 12Canadians are randomly selected.a. Let X be the number of right-handed Canadians being selected. Find the probabilitydistribution of X.b. What is the probability that majority of the selected Candians are right-handed.c. What is the mean and standard deviation of X.Question 3: The weight of potato chips in a medium size bag is stated to be 300 g.The amount that the packaging machine puts in these bags is believed to have be normallydistributed with mean 306 g and standard deviation of 3.6 g.a. What proportion of all bags sold are underweight?b. What is the probability that the mean weight of the three bags is below the statedamount?c. What is the probability that the mean weight per bag of a 24-bag case of potato chipsis below 300 g?Question 4: An automatic character recognition device can successfully read about 85%of hand-written credit card application.a. Three credits card applications are randomly selected. What is the probability thatthe device successfully read at least two of them?1b. Three hundred credits card applications are randomly selected. What is the probabilitythat the device successfully read at least two hundred of them? For this question, firstgiven the exact expression of the required probability. Then approximate it based onthe method you have learned in class (or in text).c. What theory did you apply to obtain the answer in part (b)? Explain by the theory isapplicable in this case.Question 5: Clearly define the variables and parameters and set up the hypotheses foreach part.a. In 2010, Bell Canada took an average 0.4 hours to respond to trouble calls. Bell Canadaobtained the data for 2014. Is there any evidence that show a change in the averageresponse time?b. US Census Bureau data show that the mean household income in the area served bya shopping mall is $42800 per year. A market research firm questions shoppers at themall to find out whether the mean household income of mall shoppers is higher thanthat of the general population.c. The average square footage of one-bedroom apartments in a new student-housing developmentis advertised to be 880 square feet. A student group thinks that the apartmentsare smaller than advertised. They hire an engineer to measure a sample of apartmentsto test their suspicion.d. To study the sleeping pattern of adolescents, a sample of 50 adolecscents, all free ofsevere illness, are randomly selected. The research believe that people with low sleepefficiency had an average of systolic blood pressure to be higher than 132 mm Hg.Question 6: A nutrition lab tested the mean sodium content of 100 hot dogs. The labreported that the mean sodium content of their sample is 322 mg with a standard deviationof 2.5 mg.a. One of the aims is to report a 95% confidence interval for the mean sodium content ofhot dogs. Is it necessary to assume the distribution of sodium content of hot dogs isnormally distributed? Why?b. Based on your result in part (a), obtain the 95% confidence interval for the meansodium content of hot dogs.c. Based on the result in part (b), is there any evidence that the mean sodium content isdifferent from the stated 325 mg on the package?d. A dietitian is interested to know if the result suggested that the mean sodium contentof hot dogs is significantly lower than the stated 325 mg on the package. What can youtell from the lab results? (You answer has to be justified based on statistics concepts.)2Question 7: Consumer Reports tested 14 brands of vanilla yogourt and found the followingnumbers of calories per serving:160 200 220 230 120 180 140130 170 190 80 120 100 170a. State all the necessary assumptions and report a 90% confidence interval for the meancalorie content of vanilla yogourt.b. A diet guide claims that you will get an average of 120 calories from a serving of vanillayogourt. Based on the given data, is there evidence that the mean calorie content isdifferent from the claim of the diet guide?Question 8: A medical researcher believes the body temperature of adults is normallydistributed with a standard deviation of 0.4oC.a. What sample size is required such that a 99% confidence interval of mean body temperatureof adults has width at most 0.06oC?b. Based on the result in part (a), is it really necessary to assume the body temperatureof adults is normally distributed? Why?3

Consider a toy small example of a directed web graph G = (V;E):(a) Suppose we assign all 18 nodes equal initial page rank values of 118 . Now supposewe apply the unscaled Page Rank algorithm to this graph. After one iteration (orround) of the algorithm, will any nodes have a page rank value of zero? If so, whichones and why? If not, briefly explain why not.(b) Answer the same question as in part (a) for both two and three iterations of unscaledpage rank.(c) When the algorithm converges (i.e., reaches equilibrium), which nodes in the graphwill have non-zero page rank values? What will their equilibrium page rank valuesbe? Briefly justify your answer.(d) Suppose we repeat part (a) but consider a variation of the graph in which a singlenode can delete a single one of their outgoing edges. Which nodes can increasetheir (equilibrium) page rank values by deleting a single outgoing edge? Brieflyjustify your answer. (Do not consider simultaneous deletion of multiple edges, justone single edge.)(e) What is the minimum number of edges that would need to be added to the graphso that every node has non-zero page rank? Briefly explain what edges would beneeded and why.(f) Suppose we use scaled Page Rank on the original graph in part (a) with scaling factors = 0:9. Which nodes will have non-zero (equilibrium) page rank values? Qualitatively,briefly describe which node will now have the highest page rank value.

/in /by

Strategic planning is more than setting goals to achieve an objective. The strategy behind the planning can be both short term and long term and encompass different areas of management throughout a company. Elon Musk, CEO of Tesla, utilizes strategic planning as a means of cutting down on expenditures. Clifford & Mejia write, “Going forward, we will be far more rigorous about expenditures. I have asked the Tesla finance team to comb through every expense worldwide, no matter how small, and cut everything that doesn’t have a strong value justification” (2018). The strategic plan for Tesla was to cut down on long-term waste.To implement his plan successfully, Elon Musk required each of his managers with short-term and long-term expenses of $1 million and above to meet with him to go over those expenses. Elon’s innovative strategy was to implement Aristotelian philosophy of “Principles First.” This philosophy relates to understanding the fundamental principles of how things work. Elon and the Principles First method encourages his leaders to understand how things work so that they can fully understand how every piece of their department affects another. By following this philosophy, Elon and Tesla are able to cut out middle men in the process. Elon was able to close gaps in his organizational structure by getting rid of anyone that did not provide value, which ended up being mostly contractors and staff not associated with value. This philosophy is also beneficial for their Forward Integration strategy, to gain ownership or increased control over distributors or retailers (David & David, p. 134, 2017). With Tesla’s ongoing structure to provide direct to consumer car sales, Elon’s leads the company with his innovative approach that has allowed savings by cutting out additional unnecessary costs. There is a lot to be learned from Elon Musk. Most importantly, I find that his approach to personally go over reports sets a good example of how a CEO should care about his company without micro-managing. Mr. Musk’s ability to be an innovative leader by using ancient Greek philosophy also shows that we can still learn from our past. Moving forward, leaders should be more innovative and open to ideas that can provide them with, not only a competitive advantage, but a leadership advantage as well.Clifford, K., & Mejia, Z., (2018) Why Elon Musk wants his employees to use an ancient mental strategy called ‘first principles’ Retrieved from https://www.cnbc.com/2018/04/18/why-elon-musk-wants-his-employees-to-use-a-strategy-called-first-principles.htmlDavid, F.
