1. Concerned for the current state of the Australian economy the Reserve Bank of Australia (RBA) has decided to reduce interest rates. Describe the mechanism that the RBA will undertake to achieve this outcome.
2. Explain how this reduced interest rate will transmit through the economy.
3. What do you think would be the impact on the economy of this policy if the velocity component of the quantity theory of money equation M*V=P*Q was much slower than anticipated?
4. What would be the likely affect if the RBA misjudged the state of the economy and it was closer to full employment than anticipated? A diagram would assist your answer here and attract more marks.

Use the following to answer questions a-d: In an August 2012 Gallup survey of 1,012 randomly selected U.S. adults (age 18 and over), 53% said that they were dissatisfied with the quality of education students receive in kindergarten through grade 12. Test, at the 5% level, if this sample provides evidence that the proportion of Americans who are dissatisfied with education in kindergarten through grade 12 differs significantly from 50%.

a. State the null and alternative hypothesis.

b. Verify that it is appropriate to use a normal distribution to compute the p-value

c. Calculate the Test statistic

d. Use Statkey to find the p-value.

e. Make a formal decision about the test.

f. What conclusion can you make in context of this problem.

In 2011, the national percent of low-income working families had an approximately normal distribution with a mean of 31.3% (The Working Poor Families Project, 2011). Although it has remained slow, some politicians now claim that the recovery from the Great Recession has been steady and noticeable. As a result, it is believed that the national percent of low-income working families is significantly lower now in 2014 than it was in 2011. To support this belief, a recent spring 2014 sample of n=16 jurisdictions produced a sample mean of 29.8% for the percent of low income working families, with a sample standard deviation of 4.1%. Using a 0.10 significance level, test the claim that the national average percent of low-income working families has improved since 2011.

8. Write a few brief sentences to state the type of test that should be performed (Student t-test or z-test – i.e. what type of data do you have? Categorical or quantitative? Discuss. Is this is a left, right or two tailed test? How do you know? Explain thoroughly.)

9. Write the assumptions and conditions of the test that justify its appropriateness.

10. Clearly identify and state the null and alternate hypothesis for this test.

11. Use technology to identify the p-value associated with the hypothesis test.

12. State the decision of the hypothesis test based on a 0.10 significance level.

13. Provide the appropriate conclusion about the claim that the national average percent of low income working families has improved since 2011.

Section on Data: Categorical and Quantitative Variables

1) How would you rank cities?

Various organizations rank cities and produce lists of the 10 or the 100 best based on various measures. Create a list of criteria that you would use to rank cities. Include at least 8 variables, and give reasons for your choices. Say whether each variable is quantitative or categorical.

Amazon regularly couriers rectangular packages overseas. The girth of a rectangular package is defined to be the perimeter of a cross section perpendicular to the length.You prefer to use Speedy Couriers for your international deliveries, but they will only carry rectangular packages where the sum of length and girth is at most 150 cm. Find the dimensions of the package with the largest volume that they will carry. Assume that the critical point gives a maximum

Describe the relationship between chemical equilibrium and the binding of hemoglobin to oxygen and explain why strong acids are good conductors of electricity and weak acid are not

please help me and explain in detail so i can understand.( preferably give examples for both questions) thanks! :)

Can someone rewrite this in past tense, passive voice?

To begin the first experiment, you must first calibrate the Spectrophotometer. First transfer water into the cuvette, wipe cuvette and place into the spectrophotometer, then calibrate the instrument. Once calibrated construct a calibration curve for the food dye dilutions of red, yellow, and blue. Begin with transferring the color dilution series to the cuvettes and wipe the cuvettes. Place a cuvette into the spectrophotometer and enter the desired analytical wavelength, in this case we started with blue, so we entered 628 nm, and press go. Measure and save the absorbance for each sample in the color dilution series. Remember when doing so to save the absorbance values in the “current data table”. After measuring the absorbance of each sample in the color dilution series, create a calibration curve with the saved data. Enter the slope for the best fit line into your notebook. Repeat for the following color dilution series. Next to determine the concentration of the unknown sample (x) we repeat the process of transferring the unknown sample into cuvette and recording the absorbance, using the correct analytical wavelength. Finally, calculate the concentration for the unknown sample using the calibration curve.

            In the second experiment prepare colored dye mixtures in a clean test tube. Using red, blue, and yellow make 3 mixtures that are different be sure to stir mixtures. Using the concentration of each colored solution, calculate the theoretical concentration for each color in the mixture and record your data in your notebook. In the next part in experimental determination of dye concentration use a pipet as you did in the first experiment, make sure you calibrate the instrument first and then measure the absorbance of each mixture using the correct analytical wavelengths given. Use the calibration curve and determine the experimental concentration of each color dye in the mixture and record each concentration. Calculate the absolute and percent errors, then evaluate the accuracy of each theoretical concentration. In the last experiment there is an unknown sample of a mixture of red and yellow food dyes. Repeat the process of measuring the absorbance of this mixture using the correct given wavelengths. Once recorded use the molar absorptivities given and calculate the concentration for each colored dye in the mixture and record in your notebook.
