Briefly describe the presentation of two people. One is diagnosed with hypochondriasis and one is diagnosed with somatization disorder.

In C++, create two vectors, one a vector of ints and one a vector of strings. The user will fill each one with data, and then your program will display the values.

1. Copy the template file /home/cs165new/check10a.cpp to your working directory.
2. For this assignment, in order to focus our practice on the syntax of the vectors, you can put all of your code in main.
3. Create and display a vector of ints as follows:
   1. Create a vector of ints.
   2. Prompt the user for ints until they enter 0, and store them in your vector.
   3. Loop through all the numbers in the vector and display each one.
   4. When you loop through, make sure to use the size of your vector in your condition (not a separate integer from above).
4. Create and display a vector of strings as follows:
   1. Create a vector of strings.
   2. Prompt the user for strings until they enter "quit", and store them in your vector.
   3. Loop through all the strings in the vector and display each one.
   4. When you loop through, make sure to use the size of your vector in your condition (not a separate integer from above).
5. You do not have to use iterators for this assignment (but you are welcome to if you would like). It can be done using the [] operator.

You are playing rock, paper, scissors (RPS) with a friend. Because you are good at predicting your friend’s strategy, there is a 60% chance each time that you play her, that you win. You play 7 games of rock, paper scissors with your friend and would like to know how many of them you win. Use this information to answer the following questions.

1. What is the random variable in this example?
a. X = number of times your friend wins at RPS
b. X = wins
c.X = times you win
d. X = number of times you win at RPS

2. What kind of random variable is X?
a. Discrete
b. Continuous - unbounded
c. Continuous - bounded

3. For this problem, what would constitute a success and what is the probability that a success occurs?
a. Your friend winds a game of RPS, 60%
b. Your friend winds a game of RPS, 40%
c. You win a game of RPS, 40%
d. You win a game of RPS, 60%

4. What is the distribution of the random variable?
a. X ~ negbin(7, 0.6)
b. X ~ binomial
c. X ~ bin(7, 0.6)
d. X ~ bin(3, 0.6)

5. What is the probability that you win exactly three of the seven games played? (To four decimal places)

6. What is the probability that you win five or fewer games? (To four decimal places)

The parking authority in downtown Halifax reported the following information for a sample of 270 customers on the number of hours cars are parked and the amount they are charged:

Standard deviation           

b-2. How would you answer the question, how long is a typical customer parked? (Round the final answer to 3 decimal places.)

The typical customer is parked for hours.

c. Find the mean and standard deviation of the amount charged. (Round the final answers to 2 decimal places.)

The team agrees that the goal is to have a winning boat ready to leave for the competition in 45 weeks at a cost of $3.2 million.

Design of the hull, deck, mast, and accessories will initiate the boat construction. After the design is complete, the hull can be constructed, the mast ordered, sails ordered, and accessories ordered. As soon as the hull is finished, the ballast tanks can be installed. Then the deck can be built. Concurrently with the deck construction, the hull can be treated with sealant. When the deck is completed and mast, sails, and accessories received, the mast and sails can be installed concurrently with the accessories. When these installations are complete, the boat can be sea-tested.

On the parallel path, choosing the crew and relocating them on site will take 6 weeks. At the same time, housing for the crew can be secured. Once the crew arrives and is housed, the training program using the old vessel will take place. After crew arrival, crew equipment can be selected and then ordered while training is underway. When training is complete, crew maintenance on the new vessel can begin. In order for the maintenance to begin, the deck must also be complete. Once crew maintenance is complete and while the boat is being sea-tested, sailing training on the new boat can be implemented. Finally, after the boat is sea-tested and sailing training is completed, regular sea training can be implemented, weather permitting.

Suppose that XTel currently is selling at $50 per share. You buy 900 shares using $36,000 of your own money, borrowing the remainder of the purchase price from your broker. The rate on the margin loan is 9%.

a. What is the percentage increase in the net worth of your brokerage account if the price of XTel immediately changes to (a) $56; (b) $50; (c) $44? (Leave no cells blank - be certain to enter "0" wherever required. Negative values should be indicated by a minus sign. Round your answers to 2 decimal places.)

b. If the maintenance margin is 20%, how low can XTel’s price fall before you get a margin call? (Round your answer to 2 decimal places.)

c. How would your answer to requirement 2 would change if you had financed the initial purchase with only $22,500 of your own money? (Round your answer to 2 decimal places.)

d. What is the rate of return on your margined position (assuming again that you invest $36,000 of your own money) if XTel is selling after one year at (a) $56; (b) $50; (c) $44? (Negative values should be indicated by a minus sign. Round your answers to 2 decimal places.)
e. Continue to assume that a year has passed. How low can XTel’s price fall before you get a margin call? (Round your answer to 2 decimal places.)

In the code cell below, use two input() commands to collect two positive, non-zero integers from the user. These values represent the starting and ending values of a range (you may assume that the first value is always strictly less than the second value).

Next, use a loop to examine and count every integer in the range (including the starting and ending values) that contains at least one 7 among its digits. When your loop ends, print the total number of integers that contain at least one 7 and no other output.

For example, the input values 42 and 75 would produce the result 9 (within that range, we have the numbers 47, 57, 67, 70, 71, 72, 73, 74, and 75).

for example:

# Assume that my_number already has a value

number_string = str(my_number)

if 7 in number_string: # Add the rest of your code below...
