Communism is a political and economic system that seeks to create a classless society in which the major means of production, such as mines and factories, are owned and controlled by the public.
Answer:
1. It reduces the probability of sampling bias.
2. A random sample will be more representative of the whole population.
3. Allows the researcher to determine the efficacy of the fertilizer.
Explanation:
Selecting a simple random simple from a large population is a widely used method in science. Researchers select a random sample so every individual, in this case seedling, has an equal chance to be selected.
Therefore, it is an accurate method that, although is not free from errors, avoids or reduces the probability of sampling bias. Selecting a truly random tomato seedling will be more representative of the whole population of seedling instead of selecting carefully a seedling that already has specific or desired characteristics. Hence, this random sampling will allow the researcher to determine the efficacy of the fertilizer.
Answer: C
Explanation: It is correct
Answer:
The answer is A: Yes, all conditions have been met.
Random: Stated
Independent: None of the samples are greater then 10 percent of total population
Normal: n>30 so its assumed to be normal.
Sample sizes don't have to be the same unless it is a Matched pair test.
Explanation:
Answer:
To calculate profit, producers subtract total costs from total income.
Explanation:
This is a basic premise of cost theory. Total revenue is obtained by multiplying the price by the quantity sold. The total cost is the multiplication of the cost of each unit by the quantity.
Profit is the decrease in revenue by cost.
