Question

1. hypothesis: if different video games are played, then the pulse rate of the player will change. the effect of different video games on the pulse rate of players. results sentence: as the video games were played, the pulse rate of the player changed. star pools produced the highest pulse rate, spacerace produced the lowest pulse rate, and scooterboy produced a moderate pulse rate. video game title conclusion paragraph: 3. hypothesis: if the concentration of chemical x is increased, then the height of plants exposed will increase. the effect of adding more chemical x on the height of plants. results sentence: as the concentration of chemical x was increased, plant height increased, but above 10% concentrations, plant height decreased. 2% 4% 6% 8% 10% 12% 14% amount of chemical x (% concentration in water solution) conclusion paragraph:

Explanation:

For the first hypothesis, the results confirm that different video games affect pulse rate, with varying magnitudes. For the second, plant height increases with Chemical X concentration up to 10% then decreases, partially supporting the hypothesis.

Answer:

Conclusion Paragraph for Hypothesis 2: The hypothesis that different video games change the player's pulse rate is supported. As observed, Star Pools produced the highest pulse rate, SpaceRace the lowest, and MoonBuggy a moderate rate, indicating varying effects of different video games on pulse rate.
Conclusion Paragraph for Hypothesis 3: The hypothesis that increasing Chemical X concentration increases plant height is partially supported. Plant height increased with concentration up to 10%, but above 10%, height decreased, showing an optimal concentration effect of Chemical X on plant growth.
