A researcher is interested in testing whether chocolate causes hyperactivity in children. To test this hypothesis, researcher recruits 16 children, gives these children chocolate, and measures their level of activity. A researcher obtains a sample mean of M = 102, with a SS = 375. The researcher finds out that the average activity level among the population is µ = 100, but is unable to find out the population standard deviation. Does the research have enough evidence to support the hypothesis that sugar causes hyperactivity among children? Use two-tailed test with alpha α=.05 What should your conclusion be? Fail to reject the null hypothesis and conclude that chocolate does not cause hyperactivity Fail to reject the null hypothesis and conclude that chocolate causes hyperactivity Reject the null hypothesis and conclude that chocolate does not cause hyperactivity
