The following observations are lifetimes (days) subsequent to diagnosis for individuals suffering from blood cancer. 116 182 255 418 441 462 517 739 744 789 807 865 924 984 1025 1062 1064 1165 1191 1222 1222 1252 1278 1290 1357 1369 1409 1455 1479 1519 1578 1578 1599 1604 1605 1697 1735 1799 1815 1853 1899 1925 1966 (a) Can a confidence interval for true average lifetime be calculated without assuming anything about the nature of the lifetime distribution? Explain your reasoning. [Note: A normal probability plot of the data exhibits a reasonably linear pattern.] O No, the sample size is not large enough for the confidence interval to be reasonable. No, the range is not large enough for the confidence interval to be reasonable. O Yes, the range is sufficiently large enough for the confidence interval to be reasonable. • Yes, the sample size is large enough for the confidence interval to be reasonable. O No, we need to assume that the population is normally distributed.
