You may need to use the appropriate appendix table or technology to answer this question. The state of California has a mean annual rainfall of 22 inches, whereas the state of New York has a mean annual rainfall of 42 inches. Assume that the standard deviation for both states is 4 inches. A sample of 32 years of rainfall for California and a sample of 48 years of rainfall for New York has been taken.

b.What is the probability that the sample mean is within 1 inch of the population mean for California? (Round your answer to four decimal places.)

c.What is the probability that the sample mean is within 1 inch of the population mean for New York? (Round your answer to four decimal places.)

d.In which case, part (b) or part (c), is the probability of obtaining a sample mean within 1 inch of the population mean greater? Why?

1. According to the Ricardian equivalence theorem, an increase in government spending (G) would:

Increase aggregate demand as consumer spending would not change

Decrease aggregate demand as consumer spending would decrease more than the increase in G

Not change aggregate demand as consumer spending would decrease by the opposite amount as the increase in G

Not change aggregate demand as household savings would decrease

2.  From a functional finance perspective, when the economy is in an inflationary gap the government should:

do nothing

run a deficit

run a surplus

run a balanced budget

Draw and explain the P-V graph for both adiabatic and isothermal processes and explain the difference.

Apex Computing is preparing for a Secret Santa gift exchange. Certain information will be gathered from each employee. Although it would be more realistic to write a program that asks a user for input, this program will just be a practice for using structures and functions so we will create the information by assigning values to the variables.

Write a program that uses a structure named EmpInfo to store the following about each employee:

Name

Age

Favorite Food

Favorite Color

The program should create three EmpInfo variables, store values in their members, and pass each one, in turn, to a function that displays the information in a clear and easy-to-read format. (Remember that you will choose the information for the variables.)

Here is an example of the output:

Name………………………………Mary Smith

Age ……………………………….. 25

Favorite food ………………… Pizza

Favorite color ……………….. Green

Make sure to put the main section of your code in the following if block:

# Type code for classes here

if __name__ == "__main__":

# Type main section of code here

(1) Build the Account class with the following specifications:

Attributes

• name (str)
• account_number (int)
• balance (float)

Create a constructor that has 3 parameters (in addition to self) that will be passed in from the user. (no default values)

Define a __str__() method to print an Account like the following

Account Name: Trish Duce

Account Number: 90453889

Account Balance: $100.00

Define a deposit() method that has 1 parameter (in addition to self) that will be passed in from the user. (no default values) The method deposits the specified amount in the account.

Define a withdraw() method that has 2 parameters (in addition to self) that will be passed in from the user. (no default values) The method withdraws the specified amount (1st parameter) and fee (2nd parameter) from the account.

(2) In the main section of your code, create 3 accounts.

• Trish Duce 90453889 100
• Donald Duck 83504837 100
• Joe Smith 74773321 100

(3) Print the 3 accounts using print(acct1)…

(4) Deposit 25.85, 75.50 and 50 into accounts 1, 2 and 3.

(5) Print the 3 accounts.

(6) Withdraw 25.85 (2.50 fee), 75.50 (1.50 fee), 50.00 (2.00 fee).

(7) Print the 3 accounts.

Output should look like the following:

Account Name: Trish Duce

Account Number: 90453889

Account Balance: $100.00

Account Name: Donald Duck

Account Number: 83504837

Account Balance: $100.00

Account Name: Joe Smith

Account Number: 74773321

Account Balance: $100.00

Account Name: Trish Duce

Account Number: 90453889

Account Balance: $97.50

Account Name: Donald Duck

Account Number: 83504837

Account Balance: $98.50

Account Name: Joe Smith

Account Number: 74773321

You will use the definition of the linked-queue from lab6, and re-write it as a template for a linked-queue (I hope you finished the function definitions)

In the driver file, create and use queues of different types to show it works.

In the documentation, indicate if there are any types it won’t work for, and why not.

A box with an inertia of 2kg is held on a 1m high table against a spring with k = 75N which is initially compressed 0.5m. The coefficient of friction between the box and the table is 0.2. The spring is released, and it pushes the box until it reaches its equilibrium length. At this point, the spring is stopped by a stopper and the box continues to slide across the table with only the force of friction acting on it. After losing contact with the spring, the box travels the distance of the rest of the table, another 0.5m, where it then flies off the end of the table and lands on the floor. Assuming no air resistance,

1. (a) What was the net work done on the box while it was being pushed by the spring?

2. (b) What was the net work done on the box from the time it left the spring until it reached the edge of the table?

3. (c) How fast was the box moving when it flew off the table?

4. (d) How far from the table did the box land?
