A scientific study conducted in 2017 wanted to determine if a person drinking soda attracts more flies than a person drinking water. The study looked at 62 adult volunteers who were randomly assigned to consume either soda or water. Their attractiveness to flies was measured by counting how many flies approached each person in a one-hour period. Of the 31 adults assigned to the soda group, they found that the average number of flies was 132. With the 31 adults assigned to the water group, they found the average number of flies was 130. The correct null and alternative hypotheses for this situation would be: Ho: Ha: Assuming the relevant p-value for this test was 0.352, complete the conclusion below: We the null hypothesis. We convincing evidence that there is a difference in the mean number of flies that were attracted when comparing soda and water drinkers.
