The quarterly returns for a group of 55 mutual funds are well modeled by a Normal model with a mean of 8.4% and a standard deviation of 1.9%. Use the 68-95-99.7 Rule to find the cutoff values that would separate the following percentages of funds, rather than using technology to find the exact values. a) the highest 50% b) the highest 16% c) the lowest 2.5% d) the middle 68% a) Select the correct choice and fill in any answer boxes in your choice below. (Round to one decimal place as needed.) O A. XS B. x2 8.4 % Oc. % SxS b) Select the correct choice and fill in any answer boxes in your choice below. (Round to one decimal place as needed.)
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.
