a) ( 0.8509718, 0.8890282)
b) ( 0.7255, 0.7745)
Explanation:
(a)
Given that , a = 0.05, Z(0.025) =1.96 (from standard normal table)
So Margin of error = Z × sqrt(p × (1-p)/n) = 1.96 × sqrt(0.87 × (1-0.87) / 1200)
=0.01902816
So 95 % confidence interval is
p+/-E
0.87+/-0.01902816
( 0.8509718, 0.8890282)
(b)
Margin of error = 1.96 × sqrt (0.75 × (1-0.75) / 1200) = 0.0245
So 95% confidence interval is
p+/-E
0.75+/-0.0245
( 0.7255, 0.7745)
Answer:
0.98
Explanation:
Computation for Bill Duke portfolio's beta
First step is to find the Investment in Y which is:
Investment in Y=100,000-35,000
=$65,000
Second step is to calculate for the Portfolio beta using this formula
Portfolio beta=Respective beta*Respective Investment weight
Portfolio beta =(35,000/100,000*1.5)+(65,000/100,000*0.7)
Portfolio beta=(0.35*1.5) +(0.65*0.7)
Portfolio beta =0.525 +0.455
Portfolio beta=0.98
Therefore the Portfolio Beta will be 0.98
Technology has changed the workplace a lot. First of all, people can work from virtually anywhere where there's internet connection. It means people can work on the go or from home almost all the time. This has allowed many companies to relocate many offices to their staff's homes, leading to substantial cuts in operation costs, to more flexibility and conviviality at the workplace.
Answer:
True
Explanation:
Business plan software have proven to be of little value in its application. This can be attributed to the fact that softwares are standardized and do not have the flexibility to stray from the provided templates. Also, business softwares restricts the user from personalizing his or her business plans according to his or her business environment or location. Finally, software designed to create business plans do not allow users to review their written works. All these contributed in making softwares designed to help create business plans difficult to apply in every business situation, thus diminishes its value.
Answer:
A. Market
Explanation:
An economy can be defined as an inter-related process of production between producers (manufacturers), distributors and consumers of goods and services, which primarily determines how scarce resources are used or allocated in a specific country. There are four (4) main types of economy and these are;
1. Traditional economy.
2. Mixed economy.
3. Command economy.
4. Market economy.
<em>A type of economy in which the largest variety of goods and services are produced is a market economy because their prices are mainly determined or dependent on supply and demand.</em>
This ultimately implies that, both supply and demand influence economic decisions such as what goods are to be produced, how many should be produced, what price should they be sold, distribution method to be used, who buys the goods etc.
Hence, a market economy is relatively free of government intervention, as well as government interference with profits and the factors of production such as land, labor, capital etc.
