The answer is: his study does not qualify as an experiment. For the study to be an experiment, Dr. Kline would have to manipulate the independent variable in a group (for example, apply a certain treatment) and also have a control group to which he doesn’t apply such treatment.
In this case, the study is an observational study because he only observed the subjects that were in the zoo that morning and measured the variable of his interest, that is the environmental attitude of the visitors, he did not apply a certain treatment to the group nor manipulate any variable.
Answer:
C. Critical
Explanation:
A non-directional hypothesis talks about how an independent variable has an effect on the dependent variable. The direction of the effect isn’t a definite one.
This form of hypothesis would entail the use of a critical test to ascertain its authenticity due to the effect not being a definite one. This means extra tests and caution are employed in this case.
This is why critical tests is the right choice.
According to human biological evaluation, Hyperventilation causes generalized <u>vasoconstriction</u> which <u>decreases</u> blood flow to the brain and can result in feeling dizzy or faint.
Vasoconstriction is a health-related condition in humans that occurs when there is a narrowing or constriction of blood vessels by small muscles in their walls.
Over the years, vasoconstriction is a result of disease, drugs, or psychological disorders.
Depending on the level of narrowness, vasoconstriction may be severe.
Hence, in this case, it is concluded that the correct answer is <u>vasoconstriction</u> and <u>decreases</u>, respectively.
