Question: Contamination of New Jersey wells. Methyl t-butyl ether (MTBE) is an organic water contaminant that often results from gasoline spills. The level of MTBE (in parts per billion) was measured for a sample of 12 well sites located near a gasoline service station in New Jersey (Environmental Science & Technology, Jan. 2005).The data are listed in the accompanying table.

1. Give a point estimate for \(\mu\), the true mean MTBE level for all well sites located near the New Jersey gasoline service station.
2. Calculate and interpret a \(99 \%\) confidence interval for \(\mu\)
3. What assumptions are required for the interval, part b, to be valid? Are these assumptions reasonably satisfied?
