a)

A sample of 12 people was asked how much change they had in their pockets and wallets. The responses (in cents) are 52 25 15 0 104 44 60 30 33 81 40 5 Determine the mean, median, and mode for these data.What is the geometric mean of the following rates of return? .50 30 -.50 -.25The following returns were realized on an investment over a 5-year period. Year 1 2 3 4 5 Rate of Return .10 .22 .06 -.05 .20 a. Compute the mean and median of the returns. b. Compute the geometric mean. c. Which one of the three statistics computed in parts (a) and (b) best describes the return over the 5-year period? Explain.An investment you made 5 years ago has realized the following rates of return. Year 1 2 3 4 5 Rate of Return -.15 -.20 .15 -.08 .50 a. Compute the mean and median of the rates of return. b. Compute the geometric mean. c. Which one of the three statistics computed in parts (a) and (b) best describes the return over the 5-year period? Explain.An investment of $1,000 you made 4 years ago was worth $1,200 after the first year, $1,200 after the second year, $1,500 after the third year, and $2,000 today. a. Compute the annual rates of return. b. Compute the mean and median of the rates of return. c. Compute the geometric mean. d. Discuss whether the mean, median, or geometric mean is the best measure of the performance of the investment
