Use the given data for creation of a table with lowest limit as the lowest value and class interval of 5. Use that table for calculation of cumulative frequency, reverse cumulative frequency, relative frequency. Use Excel for these calculations. Then calculate the mean, median and mode of the data through that frequency table by manual calculation. 58 54 85 88 89 88 82 81 77 63 86 52 48 42 69 46 41 84 40 57 57 54 60 43 62 50 73 89 56 48 52 51 83 46 81 60 85 89 51 60 58 63 42 64 76 89 80 70 41 80 74 57 79 82 77 63 69 55 90 79 67 87 48 57 81 58 68 66 61 55 48 68 56 57 89 77 86 87 49 75 73 64 50 49 80 74 80 65 79 82 46 57 81 60 80 48

Each class should contain its lower class limit and each sequential lower class limit should increase by increments of the class width. In that the data appears to be discrete, use a closed-interval to label each class. Data range Frequency

The accompanying data file shows the annual returns (in %) for a mutual fund focusing on investments in Latin America and a mutual fund focusing on investments in Canada over the past 25 years. Click here for the Excel Data File a. Which fund had the higher reward over this time period? since it has the b. Which fund was riskier over this time period? since it has the c-1. Given a risk-free rate of 2%, calculate the Sharpe ratio for each fund. What does this ratio imply? Note: Round intermediate calculations to at least 4 decimal places and final answers to 2 decimal places. Sharpe ratio for Latin America Sharpe ratio for Canada c-2. Over this time period, the Sharpe ratio implies that the: O Latin America fund had a higher reward per unit of risk. O Canada fund had a higher reward per unit of risk. O Latin America fund had the higher relative dispersion. ○ Canada fund had the lower relative dispersion.
