Question

Use the following returns for X and Y Requirement 1: calculate the average returns for x and y (Do not round intermediate calculations. enter answers as a percentage rounded to 2 decimal places (r.g., 32.16) Requirement 1: calculate the variances returns for x and y (Do not round intermediate calculations. round your answers as a percentage rounded to 2 decimal places (r.g., 32.161616) requirement e3: calculate the standard deviations for x and y (Do not round intermediate calculations. enter answers as a percentage rounded to 2 decimal places (r.g., 32.161)

Explanation / Answer

1. Return of X = (22.8% + (17.80%) + 10.80% + 21.60% + 5%)/5

= 8.48%

Return of Y = (29.40% + (4.8%) + 31.4% + (16.60%) + 35.4%)/5

= 14.96%

2. Variance of X = [(8.48 - 22.80)2 + (8.48 - (17.80)2 + (8.48 - 10.80)2 + (8.48 - 21.60%)2 + (8.48 - 5)2]

= 2158.55

Variance of Y = [(14.96 - 29.40)2 + (14.96 - (4.80)2 + (14.96 - 31.40)2 + (14.96 - (16.60))2 + (14.96 - 35.4)2]

   = 2283.07

3. Standard deviation of X = (2158.55)1/2

   = 46.46%

   Standard deviation of Y = (2283.07)1/2

= 47.78%
