A health officer is trying to study the malaria situation of Africa. From the records of seasonal blood survey (SBS) results he came to understand that the proportion of people having malaria in Africa was 3.8% in 1978 BC. The size of the sample considered was 15000. He also realized that during the year that followed (1979BC), blood samples were taken from 10,000 randomly selected persons. The result of the 1979 BC seasonal blood survey showed that 200 persons were positive for malaria. Help the health officer in testing the hypothesis that the malaria situation of 1979 did not show any significant difference from that of 1978(take the level of significance, a= 0.1)

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.

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%

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
