A company randomly selected nine office employees and secretly monitored their computers for one month. The times (in hours) spent by these employees using their computers for non-job-related activities (playing games, personal communications, etc.) during this month are given below. Assuming that such times for all employees are normally distributed, make a confidence interval for the corresponding population mean for all employees of this company. Round your answers to two decimal places.

The yield to maturity (YTM) on 1-year zero-coupon bonds is 7% and the YTM on 2-year zeros is 8%. The yield to maturity on 2-year-maturity coupon bonds with coupon rates of 10% (paid annually) is 7.5%.

a. What arbitrage opportunity is available for an investment banking firm?

The arbitrage strategy is to buy zeros with face values of $  and $  , and respective maturities of one year and two years.

b. What is the profit on the activity? (Do not round intermediate calculations. Round your answer to 2 decimal places.)

8. Refer to the previous problem. The parent particle moves in the lab with kinetic energy 800 MeV, and one daughter particle is emitted along the parent’s direction of motion. Find the lab kinetic energy (in MeV) for the daughter emitted backwards in the parent’s rest frame.

Previous Problem: 7. A particle of rest energy 800 MeV decays in its rest frame into two identical particles of rest energy 250 MeV. What are the kinetic energies (in MeV), momenta (in MeV/c), and velocities (in units of c) of the daughter particles?

A firm is considering replacing the existing industrial air conditioning unit. They will pick one of two units. The first, the AC360, costs $26,774.00 to install, $5,198.00 to operate per year for 7 years at which time it will be sold for $6,919.00. The second, RayCool 8, costs $41,604.00 to install, $2,063.00 to operate per year for 5 years at which time it will be sold for $9,086.00. The firm’s cost of capital is 5.80%. What is the equivalent annual cost of the RayCool8? Assume that there are no taxes.

ROUND TO 2 DECIMAL PLACES. THANK YOU IN ADVANCE.

This week we will discuss the topic of energy balance. The CDC reports that obesity has reached epidemic levels and that we have basically lost the war on obesity. Something is wrong in our approach to healthy living, and we see that people can lose weight on diets but almost all regain the lost weight within 2-5 years. As a society, dieting is not working. There is a "counter-culture" movement that is gaining traction called HAES - Health At Every Size. Explore this new way of thinking about health as more than just a number on a scale.

Please respond to the following: What did you learn about HAES, and what do you think of the approach? Include in your post at least two positives to the concept and two concerns that you have on the concept?

Fill in the blanks with the given words.

In the last 40 years, the concentration of carbon dioxide in the air has increased by more than 20%. IR spectroscopy shows that carbon dioxide absorbs IR radiation.

If carbon dioxide molecules absorb IR radiation, where does that energy go? How does the increase in the concentration of carbon dioxide affect the air temperature?

If carbon dioxide molecules absorb IR radiation, the energy goes into( ___). Vibrating carbon dioxide molecules make other molecules in the air move faster. This means that the average (___)energy of the air molecules(___)and therefore the air temperature(___). Since the concentration of carbon dioxide has increased in the last 40 years, ( ___)IR radian is now absorbed leading to(___)temperatures.

Answer bank: higher, lower, potential, kinetic, increases, decreases, less, more, bond breaking, rotational motion, vibrational motion

This requires you to conduct a one-way analysis of variance.

Data are given to you on the “days on market” for a random sample of homes for sale by realtors using 5 different training programs that the realtors experienced. The 5 programs can be described as: computer-based course, campus training (on-site in a classroom), apprentice (work side-by-side with a mentor), field (solo field training), and self (a self-paced training course with books and coursework at home).

1. Present the null and alternative hypothesis for an experiment to determine if there are significant differences in the “days on market” for the realtors experiencing the different training programs.

2. Present the excel output for the one-way analysis of variance and state your decision (whether you reject or fail to reject the null) and conclusion (whether you have sufficient evidence for, or insufficient evidence for,….the alternative). Be sure to clearly state your F_computed (a.k.a. F-value) and P-value.

A researcher is interested in studying the effect that the amount of fat in the diet and amount of exercise has on the mental acuity of middle-aged women. The researcher used three different treatment levels for the diet and two levels for the exercise. The results of the acuity test for the subjects in the different treatment levels are shown below.

a) Perform a two-way analysis of variance and explain the results. (Show all work)

b) Find the effect size for each factor and the interaction and explain the results. (Show all work)
