9. Green tea has long been said to help people to lose weight. A clinic in Japan conducted a study where participants were divided into 2 groups. Group 1 consisted of people who did not drink any tea, and group 2 consisted of people who started drinking at least one cup of green tea a day. Both groups followed a similar diet and exercise routine during the duration of the study. The results of the study are shown below, showing the number of participants and the number of people who reported a weight reduction during the study: Group 1 n1 = 270 X1 = 135 Group 2 n2 = 260 X2 = 134 Based on this result, is there enough evidence at a = 0.05 level of significance to suggest that drinking green tea will help you lose weight? a.
