A random sample of 89 tourists in Chattanooga showed that they spent an average of $2860 (in a week) with a standard deviation of $126; and a sample of 64 tourists in Orlando showed that they spent an average of $2935 (in a week) with a standard deviation of $138. We are interested in determining if there is any significant difference between the average expenditures of all the tourists who visited the two cities.

How do I add an output operator to a class in C++?

The specific part of the task said to:

Define a ​class t​o hold accounts. Use the ​same​ stream variable! Write getters to access the fields in the accounts when printing. Add an output operator for your class. First, Repeat the print loop using this output operator.Now​ make the output operator a friend, by adding a friend​prototype​ to your account class definition. Add a line in the output operator that prints the fields “directly”, i.e. without using the getters. The vector push_back method will be passed as temporary object defined as the argument to push_back. Repeat the filling of the vector using ​emplace_back ​and again display the contents.

a.) Find the pressure difference on an airplane wing where air flows over the upper surface with a speed of 120 m/s and along the bottom surface with a speed of 90 m/s.
_____ Pa

b.) If the area of the wing is 25 m², what is the net upward force exerted on the wing?
____ N

(You may assume the density of air is fixed at 1.29 kg/m³ in this problem. Also, you may neglect the thickness of the wing-- though could you incorporate this too, if it was given?)

The answer is NOT a) 3.4x10^4 and b) 8.5 x 10^5. These were both incorrect.

Fincher Manufacturing (FM) is considering two mutually exclusive capital investments to
utilize an idle factory owned by the firm. The first alternative calls for manufacturing tundratorque drill bits required for the extraction of rare earth metals from the frozen tundra of
Greenland. This proposal would generate after-tax cash inflows of $12 million per year
beginning in one year (at date 1). Due to the current scarcity of rare earth metals, the yearly
cash flows for this project are expected to grow by 5 percent per year in perpetuity from date
1 on. The second alternative calls for producing the Polycrystalline Diamond Compact bits
frequently used in horizontal drilling operations. Alternative two will generate constant
yearly after-tax cash flows of $20 million beginning in one year (at date 1) and remaining
constant in perpetuity. Assuming each project requires an initial investment of $120 million:
a. Which capital investment project has the greater IRR?

b. Which project has a greater NPV if Fincher’s cost of capital is 10 percent.

c. Determine the range of estimates for Fincher’s cost of capital for which investing in the
project having the greater IRR maximizes the value of the firm.

Quincy Durant, who had his 75th birthday last month, has been offered a reverse mortgage by the Selleck National Bank. The terms of the reverse mortgage call for Mr. Durant to receive a fixed monthly income payment over his remaining 10-year life expectancy, with the monthly income payment being determined by setting the future value of the monthly payments to be received by Mr. Durant equal to 90 percent of the current $400,000 value of his home. At the end of 10 years Mr. Durant expects to sell his home and repay these monthly payments along with the accrued interest on his monthly borrowings over the previous 10 years. Assuming that that the interest rate on the reverse mortgage is 4.20 percent, compare the monthly amount that Mr. Durant will receive from the reverse mortgage with the monthly payment for a conventional 10-year mortgage loan in the amount of $360,000 with a monthly compounded interest rate of 4.20 percent.?
