Consider the following data set. 6, 6, 7, 10, 14 LA USE SALT (a) Compute the mode, median, and mean. mode median mean (b) Multiply each data value by 4. Compute the mode, median, and mean. mode median mean (c) Compare the results of parts (a) and (b). In general, how do you think the mode, median, and mean are affected when each data value in a set is multiplied by the same constant? O Multiplying each data value by the same constant c results in the mode, median, and mean increasing by a factor of c. O Multiplying each data value by the same constant c results in the mode, median, and mean remaining the same. O Multiplying each data value by the same constant c results in the mode, median, and mean decreasing by a factor of c. There is no distinct pattern when each data value is multiplied by the same constant. (d) Suppose you have information about average heights of a random sample of airline passengers.

Army NG G1 Portal Pax World Balanced is a highly respected, socially responsible mutual fund of stocks and bonds.

The mean and standard deviation of annualized percent returns are shown below. The annualized mean and standard deviation are for a recent 10-years period. t. Pax World Balanced: x = 9.52%; S = 13.86% Vanguard Balanced Index: x = 8.97%; S = 12.29% (a) Compute the coefficient of variation for each fund. (Round your answers to one decimal place.) Pax Vanguard CV |% If x represents return and s represents risk, then explain why the coefficient of variation can be taken to represent risk per unit of return. From this point of view, which fund appears to be better? Explain. O Since the CV is s/s2 we can say that the CV represents the risk per unit of return; the Pax fund appears to be better because the CV is smaller. O Since the CV is s/s2 we can say that the CV represents the risk per unit of return; the Vanguard fund appears to be better because the CV is smaller. Since the CV is s/x we can say that the CV represents the risk per unit of return; the Pax fund appears to be better because the CV is smaller. Since the CV is s/x we can say that the CV represents the risk per unit of return; the Vanguard fund appears to be better because the CV is smaller. Since the CV is s/x we can say that the CV represents the risk per unit of return; neither fund is better because the CV's are equal. Since the CV is s/s2 we can say that the CV represents the risk per unit of return; neither fund is better because the CV's are equal.

O Multiplying each data value by the same constant c results in the standard deviation remaining the same. O Multiplying each data value by the same constant c results in the standard deviation being |c) times smaller. O Multiplying each data value by the same constant c results in the standard deviation being |cl times as large. O Multiplying each data value by the same constant c results in the standard deviation increasing by c units.
