Use the five steps in hypothesis testing. 1. Agriculture: Ground Water Unfortunately, arsenic occurs naturally in some ground water (Reference: UnionCarbide Technical Report K/UR-1. A mean arsenic level of parts per billion (ppb) is considered safe foragricultural use. A well in Texas is used to water cotton crops. This well is tested on a regular basis for arsenic. Arandom sample of 37 tests gave a sample mean x̄ = 7.2 ppb arsenic, with s= 1.9 ppb. Does this information indicate that the mean level of arsenic in this well is less than 8 ppb? Use a= 0.01
