<u>Solution and Explanation:</u>
a) 51% of users of mobile phones use their phone at least once per hour,
It is a binomial distribution with n = 150, p = 0.51
mean = np = 150 multiply with 0.51 = 76.5
SD= sqrt(np(1-p) )= 6.1225
Since np and n(1-p) > 5, we can assume the distribution is normal.
B) please see the attached file.
c) It is a binomial distribution with n = 150, p = 0.02
mean = np = 150*0.02 = 3
SD= sqrt(np(1-p) )= 1.71464
Since np < 5, we cannot assume the distribution is normal.
Answer:
The statement is true
Explanation:
Tightening monetary policy or curbing money supply in an economy is a move by Federal Reserve to control inflation or bring down over-heated economic growth.
Money supply is curbed by increasing short-term interest rates, thereby increasing cost of borrowing and making borrowing less attractive to public. This increase in short-term rates, also called Federal fund rates are usually greater than long-term interest rates prevailing in the market.
0.08x+0.085 (10000-x)=842.50
Solve for x
X= 1500 invested at 8%
10000-1500=8,500 at 8.5%
Answer: Option E
Explanation: In a free market system the prices of goods and services produced are determined by the market forces of demand and supply. This are also known as open market.
The intervention of govt. in regulating such markets is very minimal. Thus, the control in such markets stands in hands of private owners. Therefore, the private owners produce with the single aim of profit maximization in such economies.
Hence we can conclude that the right option is E.
