n the study that measured anxiety/fear in 12 arachnophobes in two situations: playing with a spider vs. viewing pictures of spider, which is true about the 95% Confidence Interval Error Bars (around the two means- use the Descriptive Plot) A) The two 95% confidence interval error bars overlapped, but by much less than half of the bars. The small amount of overlap (~less than 25% overlap) indicates a statistically significant mean difference between the two conditions. B) The two 95% confidence interval error bars didn't overlap at all. This indicates there was no statistical significance. C) The two 95% confidence interval error bars overlapped, but by much less than half of the bars. The small amount of overlap (~less than 25% overlap) indicates there was no statistically significant mean difference between the two conditions. D) The two 95% confidence interval error bars didn't overlap at all. This indicates a statistically significant mean difference between the two conditions.
