Question

In an experiment, 30 squid are given vitamins and 30 squid are not

given vitamins, in order to see if vitamins allow squid to make more
ink. It was found that the average amount of ink produced in the
control group (no vitalnins) was 20 ml per squid. The average in the
experimental group was 30 ml. Which of the following is a reasonable
conclusion?
A. Vitamins have no effect on squid ink production.
B. Squid should be given vitamins every day.
C. Vitamins seem to cause an increase in ink production.
D. Squid that use vitamins are healthier than squid that don't use
vitamins.

Answer 1

The most reasonable conclusion from the experiment is that vitamins seem to cause an increase in ink production in squids.

Step-by-step explanation:

Based on the results of the experiment where 30 squid were given vitamins and 30 were not, and the group given vitamins produced more ink on average, a reasonable conclusion would be that vitamins seem to cause an increase in ink production. Therefore, the correct answer is C. Vitamins seem to cause an increase in ink production. Answer A is incorrect because there is a difference in ink production between the two groups. Answer B jumps to a recommendation without further support or investigation. Lastly, Answer D makes a health claim that is not supported by the ink production data alone.
