uropean growth mutual fund specializes in stocks from the British Isles, continental Europe, and Scandinavia. The fund has over 450 stocks. Let dom variable that represents the monthly percentage return for this fund. Suppose x has mean u = 1.5% and standard deviation o = 1.3%. (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 reasonable to assume that x (the average monthly return on the 450 stocks in the fund) has a distribution that is approximately normal? Ex Yes ,x is a mean of a sample of n = 450 stocks. By the central limit theorem ♥ , the x distribution is 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 decimal places.) |x

Permutations and Combinations

If there are 5 dishes, they can be relished in any order at a time. In permutation, it should be in a particular order. In combination, the order does not matter. Take 3 letters a, b, and c. The possible ways of pairing any two letters are ab, bc, ac, ba, cb and ca. It is in a particular order. So, this can be called the permutation of a, b, and c. But if the order does not matter then ab is the same as ba. Similarly, bc is the same as cb and ac is the same as ca. Here the list has ab, bc, and ac alone. This can be called the combination of a, b, and c.

Counting Theory

The fundamental counting principle is a rule that is used to count the total number of possible outcomes in a given situation.
