The Umbrella Corporation has the following Income statement and balance sheet for 1993. The firm paid out 50% of it's Net Income as Dividends. What is the firms Cash Flow From Assets from the Free Cash Flow Perspective? (in this problem you must use the Free Cash Flow method to get CFFA, using the Investors perspective method will not give you the same answer due to the limitations of the system.)

Let's say you deposited ​$150,000 in a 529 plan​ (a tax advantaged college savings​ plan) hoping to have ​$410,000 available 15 years later when your first child starts college. ​ However, you​ didn't invest very​ well, and 2 years later the account balance dropped to ​$130,000. ​ Let's look at what you need to do to get the college savings plan back on track. a.  What was the original annual rate of return needed to reach your goal when you started the fund 2 years​ ago? b. With only ​$130,000 in the fund and 13 years remaining until your first child starts​ college, what annual rate of return would the fund have to make to reach your ​$410,000 goal if you add nothing to the​ account? c.  Shocked by your experience of the past 2 ​years, you feel the college fund has invested too much in​ stocks, and you want a​ low-risk fund in order to ensure you have the necessary ​$410,000 in 13 years. You are willing to make​ end-of-the-month deposits to the fund as well. You find you can get a fund that promises to pay a guaranteed annual return of 4.5 percent which is compounded monthly. You decide to transfer the ​$130,000 to this new fund and make the necessary monthly deposits. How large of a monthly deposit must you make into this new​ fund? d.  After seeing how large the monthly deposit would be​ (in part c of this​ problem), you decide to invest the ​$130,000 today and ​$400 at the end of each month for the next 13 years into a fund consisting of 50 percent stock and 50 percent bonds and hope for the best. What APR would the fund have to earn in order to reach your ​$410,000 ​goal? -Round to two decimal places

When flights are delayed, do two of the worst airports experience delays of the same length? Suppose the delay times in minutes for seven recent, randomly selected delayed flights departing from each of these airports are as follows.

Use the MWW test to determine if there is a difference in length of flight delays for these two airports. Use α = 0.05.

State the null and alternative hypotheses.

H₀: The two populations of flight delays are identical.
H_a: The two populations of flight delays are not identical.H₀: The two populations of flight delays are not identical.
H_a: The two populations of flight delays are identical.    H₀: Median delay time for airport 1 − Median delay time for airport 2 ≤ 0
H_a: Median delay time for airport 1 − Median delay time for airport 2 > 0H₀: Median delay time for airport 1 − Median delay time for airport 2 < 0
H_a: Median delay time for airport 1 − Median delay time for airport 2 = 0H₀: Median delay time for airport 1 − Median delay time for airport 2 ≥ 0
H_a: Median delay time for airport 1 − Median delay time for airport 2 < 0

Find the value of the test statistic.

What is the p-value? (Round your answer to four decimal places.)

p-value =

What is your conclusion?

Reject H₀. There is sufficient evidence to conclude that there is a significant difference in length of flight delays for these two airports.Do not reject H₀. There is not sufficient evidence to conclude that there is a significant difference in length of flight delays for these two airports.    Reject H₀.
