how a mutual fund is structured. Make sure to explain why mutual fund fee's may or may not be worth the cost to you. Comment on why you might want to invest in a mutual fund instead of a good stock. Do not take any short cuts answering this question this week, I want detail. This is the investment tool that most individuals use. The companies provide detailed information for you to review every month. There are many types of mutual funds and various costs. Some mutual funds are conservative some mutuals funds are aggressive.

A Field Poll Survey reported that 53% of registered voters in a state approved of allowing two people of the same gender to marry and have regular marriage laws apply to them. Among 18 to 39 year olds (registered voters in this state), the approval rating was 72%. Six in ten registered voters in this state said that the upcoming Supreme Court's ruling about the constitutionality of a proposition was either very or somewhat important to them. Out of those registered voters who support same-sex marriage, 71% say the ruling is important to them. In this problem, let the following apply.

• C = registered voters who support same-sex marriage

• B = registered voters who say the Supreme Court's ruling about the constitutionality of the proposition is very or somewhat important to them

• A = registered voters who are 18 to 39 years old.

Find P(C|A). (Enter your answer to two decimal places.)

Find P(C OR B). (Enter your answer to four decimal places.)

A climate study compared temperature differences in 1948 vs. 2018. Scientists sampled 197 locations from the National Oceanic and Atmospheric Administration’s (NOAA) historical data, where the data was available for both years of interest. The scientists wanted to know: were there more days with temperatures exceeding 90°F in 2018 or in 1948? For each of the 197 locations, they calculated the difference in number of days exceeding 90°F (number of days in 2018 – number of days in 1948). The average of these differences was 2.9 days with a standard deviation of 17.2 days.

Is there a relationship between the observations collected in 1948 and 2018? Or are the observations in the two groups independent? Explain.

Write research and null hypotheses for this study in symbols and words. HINT: make sure to read the problem carefully.

Find the critical value. Use α = .05.

Calculate the test statistic.

Make your decision about H0 and write a sentence to interpret the result of the test.

What type of error might you have made in this statistical test? Use the context of the problem to explain what this error would mean.

Based on the results of this hypothesis test, would you expect a 95% confidence interval for the average difference between the number of days exceeding 90°F in 1948 and 2018 to include 0? Explain your reasoning.

Leverage can also impact you in your personal life. Explain how you can use it to your advantage.

        Leverage can be useful in life. For example, using a credit. It gives you the opportunity to buy things now and pay later. It allows people to buy more things and save their cashflow. However, it does come at this risk of defaulting on minimum payments and causing interest on those missed payments. It will also increase the amount of debt you have. Leverage in my personal life can be great if used with good judgement and financial moves. It is always good to be cautious when using financial leverage to avoid unnecessary risk.

Compare and contrast the views of new classical economists and mainstream economists on the issue of policy rules versus the use of discretionary monetary and fiscal policy. 2. What rationale does rational expectations theory provide for the ineffectiveness of discretionary policies?3. What have been the changes or modifications in thinking about monetary rules in recent decades? 4. Explain the mainstream economists’ justification for the use of discretionary fiscal and monetary policy and their criticisms of policy rules.

A problem with a phone line that prevents a customer from receiving or making calls is upsetting to both the customer and the telecommunications company. The following data sets contain samples I have 20 problems reported to two different offices of a telecommunications company and the time to clear these problems (in minutes) from the customers lines:

Central Office 1 time to clear problems (minutes):

1.48 1.75 0.78 2.85 0.52 1.60 4.15 3.97 1.48 3.10

1.02 0.53 0.93 1.60 0.80 1.05 6.32 3.93 5.45 0.97

Central Office 2 time to clear problems (minutes):

7.55 3.75 0.10 1.10 0.60 0.52 3.30 2.10 0.58 4.02

3.75 0.65 1.92 0.60 1.53 4.23 0.08 1.48 1.65 0.72

A.)At the 0.05 level of significance, is there evidence of a difference in the variability of the time to clear problems between the two central offices?

B.)Determine the p-value and interpret its meaning.

C.)What assumption do you need to make in (a) about the two populations in order to justify your use of the F test?

D.)Based of the results of (a) and (b), which t test defined in Section 10.1 should you use to compare the mean time to clear problems in the two central offices?

Dakota Drapers supplies custom-fitted curtains and blinds to retail customers. It has recently expanded to offer a wide variety of home decorating products through its six stores across the state. After some initial problems with inventory control, the client installed a new automated inventory system in April this year (the fiscal year end is December 31). The system replaced another automated system that had been modified so often over the years that the auditors had advised Dakota’s management that they did not regard it as reliable. That is, in the past, the auditors were unable to rely on the old system sufficiently to assess control risk for inventory as anything less than high.

-Explain the normal process an auditor would expect to find in the client’s system governing changes to software applications. Why is an auditor concerned about application changes?

-Dakota Drapers’ fiscal year-end is December 31. Does the auditor need to obtain evidence about the performance of the inventory control system from every month in the year or from a sample of months? Explain.

-If the auditor conducts tests of the inventory controls at an interim date, is it appropriate to conclude that the controls are effective up through the end of period date? Explain your reasoning.

In addition to risk-free securities, you are currently invested in the Tanglewood Fund, a broad-based fund of stocks and other securities with an expected return of 11% and a volatility of 24%. Currently, the risk-free rate of interest is 4%. Your broker suggests that you add a venture capital fund to your current portfolio. The venture capital fund has an expected return of 22%, a volatility of 80%, and a correlation of 0.2 with the Tanglewood Fund. Assume you follow your broker's advice and put 50% of your money in the venture fund:

a. What is the Sharpe ratio of the Tanglewood Fund? (The Sharpe ratio of the Tanglewood Fund is 0.29. )

b. What is the Sharpe ratio of your new portfolio? (The Sharpe ratio of your new portfolio is 0.28.)

c. What is the optimal Sharpe ratio you can obtain by investing in the venture fund? (Hint: Use Excel and round your answer to two decimal places.)

Part (b): Reversing the order of bits in a word

Recall that in our course we define a word to be a 32-bit sequence (i.e., four

consecutive bytes). For some algorithms it is useful to have a reversed version of

that 32-bit sequence. (The deeply curious can read a brief description about such

use in Fast Fourier Transform algorithm implementations by visiting Wikipedia at

this link: http://bit.ly/2rnvwz6 ).

Your task for part (b) is to complete the code in reverse.asm that has been

provided for you. Please read this file for more detail on what is required.

Some test cases are provided to you.

# Compute the reverse of the input bit sequence that must be stored
# in register $8, and the reverse must be in register $15.
