Average population earnings per share for financial service corporations such as American Express, E * Trade Group, Goldman Sachs and Merril Lynch were $ 3 (Business Week, August 14, 2000). In 2001, the following earnings per share data were obtained for a sample of 10 financial services corporations:

Perform the required analysis to determine if the average population earnings per share in 2001 differ from the three dollars reported in 2000, with a 5.0% margin of error.

The following equation represents the decomposition of a generic diatomic element in its standard state.

1/2 X₂ (g) = X (g)

Assume that the standard molar Gibbs energy of formation of X(g) is 5.40 kJ·mol–1 at 2000. K and –53.08 kJ·mol–1 at 3000. K. Determine the value of K (the thermodynamic equilibrium constant) at each temperature.

K at 2000. K = ?

K at 3000. K = ?

Assuming that ΔH°rxn is independent of temperature, determine the value of ΔH°rxn from these data.

ΔH°rxn = ? kj x mol^-1

You have 2 diffraction gratings, one with 2000 lines/cm, the other with 5000 lines/cm. You are also given a light source that emits 450 nm blue light and 530 nm green light at the same time. A. What is the line spacing for each grating? B. What is the difference in the angle of the 2nd order maximum for each wavelength if you use the 5000 line/cm grating?? C. Which color is closer to the center of the diffraction pattern? D. Would the 2000 lines/cm grating result in a larger, a smaller, or the same separation?

A stock was priced at $150 per share at the end of 1999. The following table shows dividends per share paid during each year and the price of the stock at the end of the year for the following four years:

year divedends paid during year stock price at end of year

2000 $3.00 $125

2001 $3.00 $150

2002 $3.50 $155

2003 $4.00$200

For each year from 2000 to 2003, calculate the dividend yield, the capital-gains yield, and the total return to the stock. Express your calculations in percentage terms

In a survey to determine whether the daily caloric intake of the adolescent girls in
Ahafo-Ano South district of Ashanti is less than 2000 kcal, a sample of 500 adolescent
girls were randomly sampled for the study. The mean daily caloric intake from this
sample was 1985 kcal, with a standard deviation of 210 kcal. Let α = 0.05. Assume
you do not know the population variance; can the researchers conclude that the
population mean is less than 2000 kcal

please show all workings step by step using the 9 steps in hypothesis testing!

The lifetime of a particular bulb is a random variable with an average of μ = 2000 hours and a standard deviation of σ = 200 hours.

(a) What is the probability that a bulb has a lifetime between 2000 and 2400 hours?

(b) What is the probability that a bulb will last less than 1470 hours?

(c) In the case that a bulb lasts for more than 2100 hours, the probability that it will last more than 2300 hours You calculate.

(d) the probability of a bulb lasting less than 2150 hours when it lasts for more than 2050 hours. You calculate.

Using excel, find the price of a 20-year $2000 par bond with 6% annual coupons for yield rates starting at 0 and increasing by .001 (.1%) until .15 (15%). Graph the bond prices (price on the y-axis and yield on the x-axis). Answer the following questions:

1. Describe your graph. What happens to bond prices when rates increase?
2. At what rate does the bond sell for par? (When is the price $2000)?
3. At what rates is the bond selling for a discount? Why is this happening?
4. At what rates is the bond selling at a premium? Why is this happening?
