No If the TRUE variance of the sampling distribution was known, then it would be appropriate to use a t, distribution to construct confidence intervals for the mean. Yes A "statistically significant" result is one that is unlikely under assump- True False tions we made about the theoretical world. Suppose that we are interested in testing the following hypotheses about a proportion: Họ : p = 0.4 versus Ha : p < 0.4. Some data are collected and the value of the test statistic is 1.2. Should the conclusion at Yes No a = 0.05 be to reject Ho?
