Statistics Test
For a given set of returns data, converting the data from returns, to returns measured in percent will result in a sample mean and sample standard deviation that is 100 times larger.
True
False
If a histogram has a long right tail and short left tail, the median will be above the mean.
True
False
If the sample covariance is near 1 then there must be a very strong positive relationship between the two variables.
