Question

(a), (b), (c)

A European growth mutual fund specializes in stocks from the British Isles, continental Europe, and Scandinavia. The fund has over 450 stocks. Let x be a random variable that represents the monthly percentage return for this fund. Suppose
x has mean u = 1.3% and standard deviation o = 1%.
(a) Let's consider the monthly return of the stocks in the fund to be a sample from the population of monthly returns of all European stocks. Is it reasonable to assume that x (the average monthly return on the 450 stocks in the
fund) has a distribution that is approximately normal? Explain.
--Select---v, x is a mean of a sample of n = 450 stocks. By the ---Select---
v, the x distribution ---Select--- approximately normal.
(b) After 9 months, what is the probability that the average monthly percentage return x will be between 1% and 2%? (Round your answer to four decimal places.)
(c) After 18 months, what is the probability that the average monthly percentage return x will be between 1% and 2%? (Round your answer to four decimal places.)
(d) Compare your answers to parts (b) and (c). Did the probability increase as n (number of months) increased? Why would this happen?
O Yes, probability increases as the mean increases.
O No, the probability stayed the same.
O Yes, probability increases as the standard deviation decreases.
O Yes, probability increases as the standard deviation increases.
(e) If after 18 months the average monthly percentage return x is more than 2%, would that tend to shake your confidence in the statement that u = 1.3%? If this happened, do you think the European stock market might be
heating up? (Round your answer to four decimal places.)
P(x > 2%) =
Explain.
O This is very unlikely if u = 1.3%. One would suspect that the European stock market may be heating up.
O This is very unlikely if u = 1.3%. One would not suspect that the European stock market may be heating up.
O This is very likely if u = 1.3%. One would not suspect that the European stock market may be heating up.
O This is very likely if u = 1.3%. One would suspect that the European stock market may be heating up.
