The null and alternate hypotheses are: h0 : μ1 = μ2h1 : μ1 ≠ μ2a random sample of 12 observations from one population revealed a sample mean of 25 and a sample standard deviation of 3.5. a random sample of 9 observations from another population revealed a sample mean of 30 and a sample standard deviation of 3.5.at the 0.01 significance level, is there a difference between the population means? state the decision rule.
a. state the decision rule. b. compute the pooled estimate of the population variance. c. compute the test statisticd. state your decision about the null hypothesis. e. the p-value is

answer: 230 miles ( vote ! )

step-by-step explanation:

180.39 minus 17.99 equals 162.4

then divide 162.4 by .80 to get 230

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%
