Create two posts, each with an answer to these questions:

1. What is “The Fed”? What are its functions? What changes in the functions of The Fed arose through the Financial Crisis? I am particularly interested in the third part of this question. Use support from your text and one citation.
2. Below are two hypothetical ways The Fed may be appointed. Would you favor either one of these two methods over the present method? Why or why not? In your answer, describe how the Chair and Board of Governors of The Fed is currently selected and use one outside citation to support your argument regarding your thoughts on The Fed appointment options below.
   • Upon taking office, the U.S. president appoints 7 people to the Federal Reserve Board, including a chair. Each appointee must be confirmed by a majority vote of the Senate, and each serves the same 4-year term as the President.
   • Congress selects 7 members from its ranks (4 from the House of Representatives and 3 from the Senate) to serve at its pleasure as the Board of Governors of the Federal Reserve System.

Create one thread in response to each of the above questions. Each thread should be at least 150 words

You measure 22 textbooks' weights, and find they have a mean weight of 44 grams. Assume the population standard deviation is 12.5 grams. Based on this, construct a 95% confidence interval for the true population mean textbook weight. Assume n is sufficiently large so the normal test can be used.

Give your answers as decimals, to two places

A batted baseball is hit with a velocity of 44 m/s, starting from an initial height of 4 m. Find how high the ball travels in two cases:

(a) a ball hit directly upward and

(b) a ball hit at an angle of 69° with respect to the horizontal.

Also, find how long the ball stays in the air in each case.

case a:

case b:

Write a program that tells the user if a city of their choice is in a tropical, temperate, or polar region. Use the cities.txt file provided in the Files section of this class. Your program should read the data in that file, find the city given by the user, and return a text message with the information. If the city is not found, your program should write a message accordingly. To decide which region each city falls into, use the table below.

HINT: If you follow the file reading methods explained in our video tutorial, your data will be in cell format. There are a few functions that could be very useful in this case: strcmp compares two strings (one of which can be in a cell) to see if they match. Also, cell2mat converts a cell array into an ordinary array. Finally, find finds indices and values of any non-zero elements in an array.

See the output examples below:

What city are you interested in? Caracas
Caracas is in a tropical region 

What city are you interested in? Merced
City not found!

A water trough is 8 m long and has a cross-section in the shape of an isosceles trapezoid that is 30 cm wide at the bottom, 80 cm wide at the top, and has height 50 cm. If the trough is being filled with water at the rate of 0.1 m³/min how fast is the water level rising when the water is 40 cm deep?

Suppose you apply a 5-year bank loan of $500000 at 12% APR, repayable in equal installments at the end of each month.

a. How much do you need to pay each month?

b.How much is owed (to the bank) at the end of year 3?

c. How much interest is paid at the first month of year 4 of the loan? d. How much interest is paid over the last two years of the loan? (Round up your answer to the

nearest two decimal

d. How much interest is paid over the last two years of the loan? (Round up your answer to the nearest two decimal

Q2: Professor Fair believes that extra time does not improve grades on exams. He randomly divided a group of 300 students into two groups and gave them all the same test. One group had exactly 1 hour in which to finish the test, and the other group could stay as long as desired.

The results are shown in the following table.

Test at the 0.01 level of significance that time to complete a test? and test results are independent?.

*Do not generate the table by using Excel

The following table is from a publication. The individuals in the following table have an eye irritation, a nose irritation, or a throat irritation. They have only one of the three. Is there sufficient evidence to reject the hypothesis that the type of ear, nose, or throat irritation is independent of the age group at a level of significance equal to 0.05?

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


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