Sample calculation of standard deviation.Average Bubble Volume:(x1+x2+x3)/3CarrotCarrotCarrot(17.8 + 19.0 +20.0)/3=18.9Standard deviation: (17.8-18.9)^2+(19.0-18.9)^2(20.0-18.9)^23-1= 1.2151.21518.919.315.51.521.43EXPERIMENT 747 Discussion Questions1. What was your hypothesis?2. Was your hypothesis validated based on the experimental results? Explain why. 3. How could the design of the experiment have been improved?The more mass of carrots we use, the higher the volume of bubbles will be.Based on the data we collected, our hypothesis was correct. The volume of the bubbles was almost always larger when there were more carrots. We could have used a more precise way of measuring the volume of bubbles, the mass of carrots, and the amount of soap. We could have been more careful when timing when to put the carrots in the H202 and
