Do you disagree? For each of the following statements, comment on whether you agree or disagree. If you disagree, explain why.

(a) In terms of resistance to extreme/unusual observations, the sample mean and variance are very resistant.

(b) When comparing the means from two populations, a test equivalent to the two-sample t test is to construct a 95% confidence interval for each population mean and reject the null hypothesis that the means are the same if the confidence intervals do not overlap.

(c) Given a 95% confidence interval for μ1 - μ2, one can determine whether to reject or fail to reject the hypothesis that the means are the same at the α = 0.05 significance level.
