Given the following historical returns, what is the standard deviation?  Year 1 = 9%; year 2 = -11%; year 3 = 8%; year 4 = -12%; and year 5 = -9%. The correct answer is 10.56%. How was that found

Assume the mean and standard deviation of sample returns are​ 8% and​ 10% respectively. Assuming that the returns are normally​ distributed, what is the probability of an actual return below​ 8%?

TSLAZ had returns of 0.03, 0.06, 0.12 and -0.1 during the last four "periods". Can you calculate the standard deviation of the returns? Type your answer as decimal (i.e. 0.052 and not 5.2%). Round your answer to the nearest four decimals if needed.

A population data set has a mean of 81 and a standard deviation of 5.2 find the z-scores for each of the following.Round to the nearest hundredth . a.x=72 b.x=84

Using the following annual returns, calculate the estimates of the arithmetic mean returns, the variances, and the standard deviations for assets X and Y. Also calculate the estimates of the covariance and correlation between X and Y. These five years are a sample of the entire population of returns for X and Y. Year 2001 2002 2003 2004 2005 Returns X 11% 6% -8% 28% 13% Y 36% -7% 2% -12% 43% A stock has had returns over the past six years of 29%, 14%, 23%, -18%, 9%, and -14%. What was its arithmetic mean and geometric mean returns over that period? What was the standard deviation of its returns over this six-year period?

For a set of positively correlated data, you calculate that 84% of the variation in the dependent variable is explained by variation in the independent variable. What is the correlation coefficient(r)? (round to 3 decimal places)
