Which of the following is a reason why a researcher may design an experiment with more than two levels of an independent variabl

e? A design with only two levels of an independent variable cannot provide much information about the exact form of the relationship between the independent and dependent variables. When there are only two levels of an independent variable, the relationship between the independent and dependent variables cannot be described with a straight line. An experiment with only two levels of one independent variable always tends to show that there is a positive relationship between the independent and dependent variables. An experimental design with only two levels of the independent variable can only detect curvilinear relationships between the independent and dependent variables.

Answer:

A design with only two levels of an independent variable cannot provide much information about the exact form of the relationship between the independent and dependent variables.

Explanation:

Researchers use multiple levels of an independent variable to produce every possible combination, which is then used as a condition in the experiment. It is important not to confuse having multiple independent variables with having more than two levels of independent variable. For example, if we want to study the impact of income level of parents on the expenditure of student, we know that the independent variable here is the income level, however, we could proxy it into low income level, medium income level, and high income level. The three levels of the independent variable could be individually correlated and regressed against the dependent variable, which is the student expenditure.

An Australian company produces boomerangs. They
Finger [1]

Answer:

Answer = 25 dollars

Explanation:

There is A LOT of excess information in this problem. Because of this, I shall show you how much of the information actually isnt needed. The bolded text is what is important to your question:

An Australian company produces boomerangs. They

charge $24 for their standard boomerang. This covers

their cost of materials, labor, factory, and distribution,

plus 10% profit.

A foreign company makes boomerangs, and they want

to export them to Australia because they want to sell

them for less than the Australian company. Perhaps

the foreign company pays its workers less...perhaps

its taxes are less because the foreign country doesn't

provide universal healthcare and quality education.

Perhaps the foreign company just can get materials at

lower costs. In any case, to cover its production and

distribution costs, plus profit, the foreign company only

plans to charge $20 per boomerang.

Question: If the foreign company would charge $20 per boomerang, but a 25% tariff is added to the cost, how much must the foreign company now sell its boomerangs for to cover its costs?

Unless I am doing this incorrectly, only two half-sentences are needed to answer this question. :3

Now, lets sort out this information:

Each boomerang would orginally have costed $20.

The price must increase by 25% to cover the tariff(import taxes).

To answer this question, the boomerangs need to cost 25% more, or 125% of the $20 they orginally costed.

125% of 20 can be visualized as:

1.25x20(since 125% = 1.25). 1.25*20 = 25, and thus, our answer is 25.

Hope this helps! :3
