Question: An  outbreak of food-borne illness was attributed to Salmonella.  Epidemiologists determined that the outbreak was caused by ice cream  from one company. They sampled 9 production runs and found the level of  Salmonella in MPN/g to be:
.593    .142    .329     .691    .231     .793     .519     .392     .418
At Alpha = .01, can we conclude that the average is greater than .3 MPN/g (this level is considered dangerous)?
