Many ancient tombs were cut from lime stone rock that contained uranium. Since most such tombs are not well
ventilated, they may contain radon gas. In one study, the radon levels in a sample of 12 tombs in a particular region were measured in becquerels per cubic meter (Bq/m^3).For this data, assume that x=3,694 Bq/m^3 and s= 1,168 Bq/m^3. Use this information to estimate, with 95% confidence, the true mean level of radon exposure in tombs in the region. Interpret the resulting interval. Assume that the sample population is approximately normal.
Question:
The confidence interval is (_,_) —- round time the nearest integer as needed.
