The following table contains the historic returns from a portfolio consisting of large stocks and a portfolio consisting of long-term Treasury bonds over the last 20 years. T-bills returns represent risk-free returns. Analyze the risk-return trade-off that would have characterized these portfolios. The following dataset is also available in Excel format in Module 3 Resources on Canvas. Returns in the dataset are in percents. For example, 31.33 means 31.33% per year.

a. Estimate the annual risk premium of large stocks, and T-bonds?. (Round your answers to 2 decimal places.)

b. Estimate the annual volatility of large stocks and long-term T-bonds, respectively. (Round your answers to 2 decimal places.)

c. Estimate the Sharpe ratio of large stocks and long-term T-bonds, respectively. (Round your answers to 2 decimal places.)

d. Now assume that you have always invested half of your wealth in the stock and the other half in the T-bonds. Estimate the Sharpe ratio of your portfolio. (Round your answers to 2 decimal places.)

I'm interested in a t-test of looking at the means for the <30 group in comparison to the other age groups. Do I need to run four t tests, one for <30 with each age group? The data below details the percentage of giving by age group for each of the 32 years listed. Thank you!

A certain company produces and sells frozen pizzas to public schools throughout the eastern United States. Using a very aggressive marketing strategy, they have been able to increase their annual revenue by approximately $10 million over the past 10 years. But increased competition has slowed their growth rate in the past few years. The annual revenue, in millions of dollars, for the previous 10 years is shown.

Using Minitab or Excel, develop a quadratic trend equation that can be used to forecast revenue (in millions of dollars). (Round your numerical values to three decimal places.)

a. Increase in the population

b. Increased cost of treatment and medical expenses

c.concerns about quality and safety of care

d. Increased chronic diseases

e. Less electronic ehealth system

DATA:

Cindy is a thirty-five-year-old volunteer in an inner-city church-sponsored preschool program. The mothers of the neighborhood are encouraged to bring their children to the program for a “time out.” Most of the children are present on an irregular basis one or two times a week.

            One day, Zach, a 2½ year-old became ill during his stay. A rash of small red spots that were not raised above the skin surface was observed during his changing, and he had a slight fever. His mother was located and encouraged to take him to the local clinic.

            Shortly after this, Cindy confirmed what she had suspected for about a month—a home pregnancy test was positive. At her visit to the obstetrician, Cindy relayed the story of Zach’s illness to the nurse when asked if she had recently been exposed to any illnesses. Cindy had not been overly-concerned about Zach’s rash but had seemed to be mildly ill herself about three weeks after that incident. The obstetrics nurse seemed to be very interested in this exposure and said that they would contact the clinic and see if Zach had visited and been diagnosed. Blood tests were also ordered for Cindy.

Laboratory Results

            The initial hemagglutination inhibition test indicated an antibody titer of 1:16. Subsequent sera collected 10 and 21 days later showed no significant change. There was no significant level of IgM-specific antibody detected.

Which of these is most characteristic of Zach’s symptoms

A man is pulling a 120 lb wooden box by a rope with a force of 80 lb along a wooden floor. The rope is 45 degrees from the horizontal. The coefficient of of dynamic friction between wood to wood surfaces is Uk=0.45. If the box initially starts from rest, what will the box's (a) acceleration,and (b) velocity after 8 sec? (c) max power and (d) average power. Make sure to have FDB and kinetic diagrams, and unit base vectors.
