Here, decisions about the mean haling rate are to be computed. Thus, the appropriate method for the inference is the t-interval.

The conditions to compute the T-interval is that either the sample size be above 30 or the population must be normal. Here, population is normal. Thus, the t-confidence interval could be computed here.
