2 Sample T-Test

*Question:* Does the rate of success differ across two groups?

No

(p = 0.21)

Confidence level:

95%

If the experiment is repeated many times, the confidence level is the percent of the time each sample's success rate will fall within the reported confidence interval.

It is also the percent of the time no difference will be detected between the two groups, assuming no difference exists.
