No hypothesis test is 100% certain. Because the test is based on probabilities, there is always a chance of making an incorrect conclusion. When you do a hypothesis test, two types of errors are possible: type I and type II. The risks of these two errors are inversely related and determined by the level of significance and the power for the test. Therefore, you should determine which error has more severe consequences for your situation before you define their risks.Type I errorWhen the null hypothesis is true and you reject it, you make a type I error. The probability of making a type I error is α, which is the level of significance you set for your hypothesis test. An α of 0.05 indicates that you are willing to accept a 5% chance that you are wrong when you reject the null hypothesis. To lower this risk, you must use a lower value for α. However, using a lower value for alpha means that you will be less likely to detect a true difference if one really exists.Type II errorWhen the null hypothesis is false and you fail to reject it, you make a type II error. The probability of making a type II error is β, which depends on the power of the test. You can decrease your risk of committing a type II error by ensuring your test has enough power. You can do this by ensuring your sample size is large enough to detect a practical difference when one truly exists.
4 Movement I think by use what make sense to you
The answer is a) True
Since Independence, almost every African country has been plagued by the cycle of Poverty.
Poverty has led to the development of a culture of bribery and kickbacks in between almost every aspect of the government.
With little investment in education and health, the average person has suffered even more.
Many African countries have taken on billions of dollars of debt that they can never pay off.
This has resulted in a 'debt trap' where the little money a country is able to generate, has to be paid in the forms of loans.
Lack of government funds, poor infrastructure, low education, high corruption has also resulted in numerous local rebels and quasi-militia factions mushrooming to challenge what they see as failed governments.
When you combine all these factors, you can see how poverty has resulted in a Pandora's box of problems for African countries.
Answer:
B option is correct of course!!
Pros. globalization represents free trade which promotes global economic growth; creates more jobs, makes companies more competitive, and lowers prices for consumers.
cons. globalization has made the rich richer while making the non rich poorer, therefore it is wonderful for managers, owners and investors but horrible for workers and nature.
