How do you determine significance based on confidence
intervals?
1. If using a ONE SAMPLE t-test, and the null hypothesis is H0:
u = 100, if the confidence interval interval contains 100 (for
instance, the interval is [70, 136]), is the result NOT
significant?
2. If using an TWO INDEPENDENT groups t-test, and the null
hypothesis is H0: u1 = u2, if the confidence interval contains 0
(for instance, the interval is [-1, 5]), is the result NOT
significant?
