Suppose that all the values in a data set are converted to  z  scores. which of the statements below is true?
the mean and standard deviation of the  z  scores will be the same as the mean and standard deviation of the original data values.
the mean of the  z  scores will be zero, and the standard deviation of the  z  scores will be the same as the standard deviation of the original data values.
the mean and the standard deviation of the  z  scores will both be 0.
the mean of the  z  scores will be 0, and the standard deviation of the  z  scores will be 1.

a. is correct

required rate of return = 0.166 = 16.6%

step-by-step explanation:

under the capital asset pricing model (capm), the required or expected rate of return for a particular security or asset is given using the formula:

required rate of return = risk-free rate + beta*(market risk premium)

we are given that;

risk-free rate = 4% = 0.04

beta = 1.4

market risk premium = 9% = 0.09

we simply plug these values into the above formula;

required rate of return = 0.04 + 1.4*(0.09)

required rate of return = 0.04 + 0.126

required rate of return = 0.166 = 16.6%
