3. This question concerns the analysis of simple random samples from two pop- ulations; the first population having a M(#1, o?) distribution and the second population having a N(#2, 02) distribution. (a) A researcher wishes to compare the means of the two populations. Based on two simple random samples from these populations, the researcher constructs 95% confi- dence intervals for the each of the population means. The researcher then makes the following claim ... as the 95% confidence intervals for the means do not overlap, we can conclude there is moderate evidence suggesting that the true means are different (p
