Answer:
Is an experimental study
Step-by-step explanation:
In an observational study you don't control any aspect of the investigation you just observe the variables that you determined since the beginning without any intervention.
In this case you are controlling who sees one or the other video, then you are controlling one of the variables that is the type of video each group sees and because of this it is an experimental study. Researchers designed an experiment to prove the null hypothesis they had.
The correct answer here is that if the skydiver is falling 176 feet per
second, he is falling 10560 feet per minute. This can be worked out
quite easily, by considering that if there are 60 seconds in a minute,
we then need to work out the proportion of 176 feet/1 sec = x/60 sec.
You then need to multiply 60 by 176 to get 10560, which is your answer.
