what is delta 0, testing the difference is 10 nu is rounded down

Variance two sample testing, slide 112. If the ratio is withing the defined percentile interval, one fails to reject the Null Hypothesis.

Credibility Interval is the probability interval of the random statistic, vice confidence interval. Slide 112
