The risks and challenges associated with performing so many hypothesis tests nearly all null hypotheses are false on a priori grounds.
A hypothesis is a supposition, an idea put forward for the purpose of discussion, that can be tested to see if it is true. Hypotheses are formed before the is implemented.
Hypotheses are usually written as if/then statements. B. If someone eats a lot of sugar, they will get cavities in their teeth. These statements identify a particular variable (in this case, eating a lot of sugar) and imply an outcome (in this case, the tooth develops cavities).
Hypotheses are used to define the relationship between two variables in an experiment. The purpose of a hypothesis is to find an answer to a question. Formalized hypotheses make us think about what kind of results we should be looking for in our experiments. The first variable is called the independent variable.

Answer:
A person whose salary has increased is able to purchase fewer goods and services.
Explanation:
Inflation is characterized by an increase in the prices of goods and services along with a reduction in the purchasing power.
Real income of an individual refers to the income which has been adjusted for the effects of inflation. Whereas, Nominal income refers to the income which is before any such adjustment for inflation.
In the given case, the nominal income has increased i.e if we ignore inflation. But while considering inflation, the real income of the individual has reduced evidenced by the fact that the purchasing power has reduced.
Answer: D. marginal product; increasing; average variable cost; decreasing
Explanation:
The Marginal product curve is hump-shaped and the marginal cost curve is U-shaped because these two move in opposite directions to each other.
If the marginal cost is decreasing therefore, the marginal product must be increasing. If the marginal cost is decreasing and the marginal product is increasing, average variable cost will have to fall because every additional unit produced incurs less cost so the average has to fall as well.
