An srs of 100 postal employees found that the average time these employees had worked for the postal service was = 7 years, with standard deviation s = 2 years. assume the distribution of the time the population of employees has worked for the postal service is approximately normal, with mean μ. are these data evidence that μ has changed from the value of 7.5 years of 20 years ago? to determine this, we test the hypotheses h0: μ = 7.5, ha: μ ≠ 7.5

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%
