a. Calculate the probability that loan i will have a real rate of return from 0.09 to 0.11. This probability is . TWO DECIMALS.
b. Continued. Find the symmetric interval (a, b) such that the probability is 0.99 that Xi will fall in this interval. Find the interval that is symmetric around the mean of the distribution of Xi. The value of “a” is . The value of “b” is . THREE DECIMALS.
c. Calculate the probability that the mean of the real rates of return on the loan officer’s eight loans will be from 0.09 to 0.11. This probability is . TWO DECIMALS.
d. Continued. Find the symmetric interval (a, b) such that the probability is 0.99 that the mean real rate of return will fall in this interval. Find the interval that is symmetric around the mean of the distribution of "Xbar". The value of “a” is . The value of “b” is . THREE DECIMALS.
e. How many loans would the entrepreneur have to make in order for the probability to be at least 0.99 that the mean real rate of return will be from 0.09 to 0.11? Call this number “n”. The value of n is . INTEGER (NO DECIMALS).
