The Food and Drug Administration (FDA) regulates the amount of mercury in consumable fish, where consumable fish should only contain at most 1 mg/kg of mercury. In Florida, bass fish were collected in 58 different lakes to measure the amount of mercury in the fish from each of the 58 lakes. Do the data provide enough evidence to show that the fish in all Florida lakes have different mercury than the allowable amount? State the random variable, population parameter, and hypotheses. The symbol for the random variable involved in this problem is            The wording for the random variable in context is as follows:          The symbol for the parameter involved in this problem is            The wording for the parameter in context is as follows:
