SOLVE: We are told to view the observations as an SRS. Use software of your choice to make a dotplot of the data and to obtain the 90% confidence interval for the parameter µμ . Can we trust the tt ‑procedures for these data? There are outliers in the data making the tt procedures not trustworthy. We cannot use the tt ‑procedures because the standard deviation of the population is not given. The data are clearly skewed, but there are no outliers. With sample size of n=29n=29 , inference is not unreasonable. Yes, since there are no strong departures from Normality.
