C) Mutual funds. They usually invest capital that has different origins (clients of an investment organization) to buy securities from different firms and create a profit from it.
Answer: 0.59 ± 0.081 = (0.671, 0.509)
Explanation:
The sample proportion, p = 118/200 = 0.59
The test statistic at 98% confidence interval is given by :
p + z*Sqrt(p(1-p)/n) ; p - z*Sqrt(p(1-p)/n)
z at 98% C.I. is 2.33
Therefore, 0.59 + 2.33 * sqrt(0.59*(1-0.59)/200) and 0.59 + 2.33 * sqrt(0.59*
(1-0.59)/200)
=0.59 + 0.081 and 0.59 - 0.081
=0.671, 0.509
I think it's a good thing and smart in some ways
