A. %. B. %. C. %. D. %. 22 A Total number of frequencies = 30. 7/30 = %. Question ID: 19692 Given the following frequency distribution: Return Frequency 10% up to 0% 5 0% up to 10% 7 10% up to 20% 9 20% up to 30% 6 30% up to 40% 3 What is the relative frequency of the 30 percent up to 40 percent return interval? A. %. B. %. C. %. D. %. C Total number of frequencies = 30. 3/30 = % Question ID: 19693 In a frequency distribution histogram, the frequency of an interval is given by the: A. width of the corresponding bar. B. sum of the width of all bars. 23 C. height multiplied by the width of the corresponding bar. D. height of the corresponding bar. D In a histogram, intervals are placed on the horizontal axis, and frequencies are placed on the vertical axis. The frequency of a particular interval is given by the value on the vertical axis, or the height of the corresponding bar. Question ID: 19695 Given the following annual returns, what are the median and mode returns, respectively? 1995: 15%, 1996: 2%, 1997: 5%, 1998: 7%, 1999: 0%. A. Median Mode % % B. Median Mode % no mode exists C. Median Mode % % D. Median Mode no median exists % B Median: Arrange the return values from largest to smallest and take the middle value: (7%), 0%, 2%, 5%, 15%. The middle value is %. Mode: The mode is defined as the value that most often shows up in a distribution. Because no return value shows up more than once, this distribution has no mode. Question ID: 19377 Given the following annual returns, what are the geometric and aritmetic mean returns, 24 respectively? 1995: 15%, 1996: 2%, 1997: 5%, 1998: 7%, 1999: 0%. A. %, %. B. %, %. C. %, %. D. %, %. D Geometric Mean: ( x x x x )1/5 –1 = –1 = % Arithmetic Mean: (15% + 2% + 5% 7% + 0%) / 5 = % Question ID: 19696 Which of the following statements regarding the geometric and arithmetic means is FALSE? A. If all return values in a distribution are equal, the geometric and arithmetic means will also be equal. B. If returns are variable by period, the geometric mean will be greater than the arithmetic mean. C. The difference between the arithmetic and geometric mean increases as variability between returns increases. D. The geometric mean is used to calculate pound rates of return. B The difference between the arithmetic mean and the geometric mean increases as variability between return values increase. If there is no variability (all values are equal), the geometric and arithmetic mean values will also be equal. If returns are variable, the geometric mean will always be less than the arithmetic mean. 25 Question ID: 18530 A stock had the following returns over the last five years: 98 percent, 50 percent, 13 percent, 62 percent, 34 percent. What is the geometric mean for this stock? A. %. B. %. C. %. D. %. A Geometric mean = ()()()()()1/5 –1 = = – 1 = x 100 = % Question ID: 18525 The annual rate of return for XYZ39。 I/Y=12/2=6。 pute FV. A. $8,446 B. $9,939 C. $8,962 D. $9,857 11 B Divide the interest rate by the number of pound periods and multiply the number of years by the number of pound periods. i=11/4=。 PMT=0。 FV=4,000。 CPT?168。 I/Y=8。 CPT PV=3,636 PV(2): N=2。 CPT I/Y=% Question ID: 20982 The HGM Co. is thinking about taking out a $100,000 loan that is to be paid off in annual (endoftheyear) payments of $12,042. If the bank agrees to lend the money at percent, pounded annually, how many years will it take HGM to pay off the loan? A. years. B. years. C. years. D. years. A I/Y=。 given this is an ordinary annuity and that an investor can earn 10 percent on her money, the future value of this annuity, at the end of 10 years, would be: A. $175,312. B. $152,500. C. $. D. $159,374. D Answer: N=10。 I/Y=。 FV=50,000。 FV=25,458。 I/Y=。ll be worth $30,000 in 9 years). Approximately what rate of return will investors be earning on these certificates? A. %. B. %. C. %. D. %. C Using your calculator: N=9。 CPT PV=36,577+5,000=$41,577. Or set your calculator to BGN mode and N=12。 PV=0。 FV=0。 CPT PV=1,653 PV(3): 0 PV(4): N=4。 CPT?168。 FV=2,000。 I/Y=10。 PMT= 500。 statement I is wrong since it’s the effective annual rate that adjusts for frequency of pounding. Question ID: 19387 A local bank advertises that it will pay interest at the rate of percent, pounded monthly, on regular savings accounts. What is the effective rate of interest that the bank is paying on these accounts? A. %. B. %. C. %. D. %. C (1+.045/12)12 1 = 1 = . Question ID: 19388 Lois Weaver wants to have $ million in a retirement fund when she retires in 30 years. If Weaver can earn a 9 percent rate of return on her investments, approximately how much money must she invest at the end of each of the next 30 years in order to reach her goal? A. $11,005. B. $50,000. C. $7,350. 13 D. $28,725. A Using a financial calculator: N=30。 CPT PMT=16,. Question ID: 18509 Given: $1,000 investment, pounded monthly at 12% find the future value after one year. A. $1, B. $1, C. $1, D. $1, A 14 Divide the interest rate by the number of pound periods and multiply the number of years by the number of pound periods. i=12/12=1
