I don’t know what are you asking, is this multiple choice. Please explain more
Answer:
(a) 
(b) 
(c) X=4.975 percent
Explanation:
(a) Find the z-value that corresponds to 5.40 percent
.


Hence the net interest margin of 5.40 percent is 2.5 standard deviation above the mean.
The area to the left of 2.5 from the standard normal distribution table is 0.9938.The probability that a randomly selected U.S. bank will have a net interest margin that exceeds 5.40 percent is 1-0.9938=0.0062
(b) The z-value that corresponds to 4.40 percent is
The net interest margin of 4.40 percent is 0.5 standard deviation above the mean.
Using the normal distribution table, the area under the curve to the left of 0.5 is 0.6915
Therefore the probability that a randomly selected U.S. bank will have a net interest margin less than 4.40 percent is 0.6915
(c) The z-value that corresponds to 95% which is 1.65
We substitute the 1.65 into the formula and solve for X.




A bank that wants its net interest margin to be less than the net interest margins of 95 percent of all U.S. banks should set its net interest margin to 4.975 percent.
Disability income insurance will provide income to a disabled or ill person with a waiting period before income is received. Commonly, when a person applies for disability income insurance and is taking out money from the government for disability there is a period of waiting. During this period they review all information given and decides whether or not the person applying actually qualifies for the funds they are wanting to receive. Most states have a set time frame they have to wait and also a set time frame of how long people can receive funds for.
Answer:
$1100
Explanation:
Compound Interest is a multiplying effect interest , in which interest for each successive period is calculated on (Principal + Interest) of each preceeding period .
Formula : A = P(1+r/n) power 'nt .
r = Interest rate , t = time , n = compound in time 't' , P = Principal
A = 1000 (1+10/1) power'(1X1) = 1000 X 11 power 1' = 1000 X 11 = 1100
