beks73 [17]

Answer:

d. if my hypothesis is correct, I can expect certain test results

Explanation:

To create a theory is not enough to state an assumption. Called scientific research, the practice tries, through a logical procedure, to produce tested, proven and safe scientific knowledge. This concept is based on the logic of scientific research that states that a hypothesis must be tested, because if the hypothesis is correct, certain test results can be expected. For this, some rules or phases are part of the process. And they are: observation, hypotheses, research method and conclusion.

Thus, we can conclude that among the alternatives presented, the one that best describes the logic of scientific investigation is the letter D.
