The following five questions  require interpretation of the graph below:    -The graph illustrates some of the study's results.The vertical lines at each data point are called error bars.As a general rule,when the error bars from two different data points or lines overlap,we can conclude that the two points or lines are not significantly different from one another.Or,put another way,we can conclude that any difference we see is due to chance,not to any real difference in the data.Given this information,which of the following best describes the results? A)  Results from the control group, the two banding groups, and the gastric bypass groups are all significantly different from one another. Gastric bypass patients lost more weight than did vertical-banded gastroplasty patients, who lost more than did banding patients, who lost more than did the control patients. B)  The gastric bypass patients lost significantly more weight than did the banding patients and the control patients. C)  The banding patients lost significantly less weight than did the vertical-banded gastroplasty patients. D)  The gastric bypass patients didn't lose significantly more weight than did the banding patients, but those both the bypass and the banding patients lost significantly more weight than did the control patients. E)  None of these accurately describes the results shown in the graph.
