Answer Happy

Question 10 1 pts Trent has developed a new line of SuperPowerMax protein shakes that he believes will lead people to increase their muscle mass faster than they drink regular protein shakes and decides to test his hypothesis using an experiment. He gives half his participants SuperPowerMax protein shakes and half traditional protein shakes and tells them he will measure their muscle mass in a month. He tells the participants receiving the SuperPowerMax protein shakes that their shakes are better for building muscle than other protein shakes and that they will definitely see results. A month later, he is happy to see that his SuperPowerMax group increased their muscle mass significantly more than the traditional protein shake group. What did Trent fail to consider? Placebo effect, because participants in the SuperPowerMax condition may have changed other behaviors because they believed that they were using a superior protein shake ● Hawthorne effect, because participants in the SuperPowerMax condition changed their behaviors because they knew Trent would weigh them a month later Nothing, believing that SuperPowerMax would increase their muscle mass would not affect the behaviors of the experimental group or the results
