Answer and Explanation:
- What was Patrick’s hypothesis? <em>Fishes that are fed with food exposed to the microwave will become smarter and will swim faster. </em>
- Which fish are in the control group? The ones that feed on regular food
- What is the independent variable? Food exposed to the microwave
- What is the dependent variable? The time fishes spend in swimming through the maze
- What should Patrick’s conclusion be? You will find the results considered in the attached file.
<em>In both groups, Patrick recorded a decrease in the time spent swimming through the maze</em>. In both groups, there were two cases in which the animal increase the swimming time. These cases could be considered as outliers. Although in general, <em>the treated group made it in a shorter time after the treatment, when comparing values before and after Patrick can not find any real difference among groups.</em> <em>His results do not show any difference,</em> hence <em>the speed and the intelligence of the animals is not influenced by the change in food, or if it is, more experimental time is required to record significant differences. </em>
