Thetreatment group was asked to wear a watch every day, and the control group was asked to avoid wearing a watch for 50 days.Researchers noted the number of occasions when students from both groups arrived later than their scheduled time.The results of the experiment showed that the mean score of the treatment group was exactly 15 points less than the meanscore of the control group. To test whether the results could be explained by random chance, the researchers created thefollowing table, which summarizes the results of 1,000 randomizations of the data with differences of means rounded to thenearest 5 points.Considen the sgnificance level to be set at 5%, so results lower than 5% can be considered statistically significant.Treahmet nin an nntni firun iounFraanu Course Activity: Treatments and Significance12 of 19E Save & ExTask 2* PrintApplying a Level of SignificanceIn this task, you'll study the data from two experiments.
