1. The return on shares of Valley Transporter is predicted under the following various economic conditions:
Recession  -0.14
Normal +0.07
Boom +0.24
If each economy state has the same probability of occurring, what is the variance of the stock?
Place your answer in decimal form using four decimal places.

2. The return on shares of the Orange Company are predicted under the following states of nature. The states of nature are all equally likely, and because there are a total of three states, each state has a 33.333% chance of occurring.

Recession  -0.14
Normal +0.07
Boom +0.20

What is the standard deviation of Orange?
Place your answer in decimal form, for example as say .0675 and not 6.75.

3. The return on the Rush Corporation in the state of recession is estimated to be -24% and the return on Rush in the state of boom is estimated to be 35%. The return on the Oberman Corporation in the state of recession is estimated to be 42% and the return on Oberman in the state of boom is estimated to be -19%. Given this information, what is the covariance between Rush and Oberman if there is a 0.70 probability that the economy will be in the state of boom and a 0.30 probability that the economy will be in the state of recession.

Place your answer in decimal form and not as a percentage.

Sketch the wave-function of the ground state of a particle of mass m which is con- fined in one dimension within a square potential well of infinite height, centred at x = 0 and of width a between x = ?a/2 and x = a/2.

What type of function is that?

If the infinite potential well is replaced by a potential well of finite height, sketch the new ground state wave-function. Explain qualitatively how the ground state energy changes in going to the finite well.

On Old Age I: A conversation with Joan Erikson

1. write a summary with two to three paragraphs explaining the views of an aging person. You may use the following questions to guide your written work:
   • How do they feel?
   • What do they think about?
   • What is important?
   • What should an aging person do?

Thank you so much for your help

For this discussion, please respond to the following:

• Think about how you listen to others. What is your listening style? How does your listening style change based on the situation?
• How can you improve listening during each stage of the listening process?
• Of the tips discussed in the video, explain two techniques you can utilize to be a better listener in the future.

1. Direct relationship: A relationship between two variables, where a change in one variable results in the same change in the other variable. For example, if one variable is increased, then the other variable will also increase.

Indirect relationship: A relationship between two variables, where a change in one variable results in the opposite change in the other variable. For example, if one variable is increased, then the other variable will decrease.

a. Considering the terms described above, do the variables of pressure and volume have a direct or an indirect relationship in Boyle’s Law? Justify your answer with data.

b. Considering what you now know about Boyle’s law, make a prediction based on the following situation: What would happen to the pressure of a gas inside a sealed bottle, if the bottle was squeezed tightly, reducing the volume of the gas by half? Explain your thoughts.

2.Using Gay-Lussac’s law, make a prediction based on the following situation: What would happen to the pressure of a gas inside a sealed bottle, if the bottle were cooled to half of its original temperature? What happens to the movement of the gas molecules in the bottle at lower temperatures? Explain how this is or is not related to the change in pressure.

3.What conditions can we use to perform the experiment investigating Avogadro’s law? Why are they necessary?

You may need to use the appropriate technology to answer this question.

To test for any significant difference in the number of hours between breakdowns for four machines, the following data were obtained.

(a)

At the α = 0.05 level of significance, what is the difference, if any, in the population mean times among the four machines?

State the null and alternative hypotheses.

H₀: μ₁ = μ₂ = μ₃ = μ₄
H_a: Not all the population means are equal.

Find the value of the test statistic. (Round your answer to two decimal places.)

18.02

Find the p-value. (Round your answer to three decimal places.)

p-value = 0

State your conclusion.

Reject H₀. There is sufficient evidence to conclude that the mean time between breakdowns is not the same for the four machines.

(b)

Use Fisher's LSD procedure to test for the equality of the means for machines 2 and 4. Use a 0.05 level of significance.

Find the value of LSD. (Round your answer to two decimal places.)

LSD =

Find the pairwise absolute difference between sample means for machines 2 and 4.

|x₂ − x₄| =

What conclusion can you draw after carrying out this test?

There is a significant difference between the means for machines 2 and 4.

There is not a significant difference between the means for machines 2 and 4.    

PART A) A sample of metal at a known hot temperature is placed in to a calorimeter containing water of known mass and known initial temperature. The temperature of the water rises and the final temperature of the water is recorded. What equation is used to calculate the amount of heat the calorimeter water absorbed?

PART B) How do you deermine the amount of heat lost by the metal if you know the amount of heat gained by the calorimeter water?

Part C) What equation is used to calculate the specific heat of the metal if you now know the amount of heat lost by the metal?
