(e) (2pts) Suppose the data are independent observations sampled from some population distribution. In which of the following circumstances we would NOT be safe to construct a one-sample t confidence interval for a population mean based on a simple random sample from a huge population? (Select one answer.) (i) The sample size is 5, and we know from past experience that the population distribution is normal. (ii) The sample size is 10, and the observations are 0, 0, 0, 0, 0, 0, 0 , 1 , 1, 18.
