Answer:
a) ![10[1-e^{-y/3} ] ^{2} e^{-y}](https://tex.z-dn.net/?f=10%5B1-e%5E%7B-y%2F3%7D%20%5D%20%5E%7B2%7D%20%20e%5E%7B-y%7D)
b) ≈ 0.76
Step-by-step explanation:
Given that : Y1 < Y2 < Y3 < Y4 < Y5 are the order statistics of five independent observations
mean of θ = 3
<u>a) Determine the P.d.f of the sample median </u>
P.d.f of sample median ( y3 ) =
attached below is the detailed solution
<u>b) determine the probability that Y4 is < 5 </u>
p( Y4 < 5 ) = G4( 5 )
= 0.7599 ≈ 0.76
attached below is the detailed solutions
Uhm ok
the answer is 5 although u probably don’t need that

Step-by-step explanation:

Answer:
a) 13913
b) 4913.82
Step-by-step explanation:
The compound interest formula is given by:

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.
In this question:
Investment of 9000, so 
Interest rate of 8%, so 
Compounded quarterly, so 
5 years and 6 months, that is, 5 years and half, so 
(a) How much would the value of her savings at the end of the term?


(b) How much is the interest earned by your savings?
The amount subtracted by the principal. So
13913.82 - 9000 = 4913.82
