1. The Odd estimator of the population average gives each odd-numbered obser- vation a weight of 2/n. Apply this estimator in the UnivariateSample sheet. What do the weights in column D look like?
2. Use the Monte Carlo simulation add-in to analyze the sampling distribution of the Odd estimator. Is it biased? What part of the Monte Carlo results did you use to answer this question?
3. Would you prefer the Odd estimator or the Sample Average estimator? Explain your choice.
4. Explore the consequences of changing the error distribution from normal to uniform in the UnivariateSample sheet. (Section 14.6 compares the normal and uniform distributions.) Replace the normalrandom formula in column B with the uniform function. What effect does this have on the sampling distribution of the Sample Average? In your answer, comment on the expected value, SE, and shape of the sampling distribution.
5. From the UnivariateSample sheet, use Excel's MEDIAN function to compute the sample median of the observed Y values. Use the Monte Carlo simulation add-in to race the Median against the Sample Average. Who wins? Why?
consider the following sample measurements 5 11 -1 8 2 7 5 1 -10 -6 4 121. determine the mean the median the range and
Based on what we watched on the last day of class, please write a one page that summarizes the primary causes of the 2007-2009 financial crisis?
The so-called too-big-to-fail policy has two conflicting sides: on one hand there's the moral hazard problem that it creates, but in the other hand the Fed must:
Vipsana's Gyros House sells gyros. The cost of ingredients (pita, meat, spices, etc.) to make a gyro is $2.00. Vipsana pays her employees $60 per day. She also incurs a fixed cost of $120 per day. Calculate Vipsana's Variable cost per day when ..
The demand for energy in the United States is often stated as persistently non-cyclical and not sensitive to both prices effects. Given such characteristics, explain the effect of each of the following on the demand or supply for gasoline.
A seller knows that there are two bidders for the object she is selling. She believes that with probability 1/2, one has a buyer value of £5 and the other has a buyer value of £10 and, with probability 1/2, one has a buyer value of £8 and the other h..
Critically evaluate the pattern of potentially anti-competitive activities by Microsoft towards its competitors. Do you think that the government should always try to eliminate monopoly power?
For every penny that the price of gasoline goes up, the U.S Postal (USPS) service experiences a monthly fuel cost increase of $8 million. State what assumptions you need to make to answer this question
How would the presence of a second technology that had higher operating costs but lower capacity costs affect peak-load pricing and investment in the capital-intensive technology?
The variable cost function of a competitive firm is given by VC = Q3- 40Q2+ 1600Q Assume the firm's fixed cost is $1,500- If the market price for a unit of Q is $1,400, determine the firm's profit maximizing level of out and its profit.
for the following set of scores compute the range the unbiased and the biased standard deviations and the variance. do
