Question

Matt is a well-known tennis player and has been approached by the manufacturers of Power Up energy drinks to endorse their beverage. They claim their drink will increase accuracy. Matt is very conscientious and doesn't want to endorse something that doesn't work. He finds that a local university did a study on energy drinks where they had participants play a computer game where they pushed a button when they saw a certain target. Then they all had a different energy drink and played the computer game again. The 25 participants who drank Power Up had a total increase in hits of 80. The 475 participants who drank other drinks had a total increase of 900 hits. Do you think Matt would be justified in saying that Power Up works better than other drinks? Why or why not?

Explanation / Answer

I think that Matt would be justified in saying that Power Up works better than other drinks,because 25 participants who drank Power Up a total increase in hits of 80, if we consider percentage of this then 320 hits increases.

Now suppose consider the other drinks, 475 participants who drank other drinks had a total increases of 900 hits, if we consider the percentage only 189 hits increases

THerefore the Matt justified in saying that Power Up works better than the other drinks
