The pH of a liquid is a measure of its acidity or
alkalinity. Pure water has a pH of 7, which is neutral. Solutions
with a pH less than 7 are acidic while solutions with a pH greater
than 7 are “basic” (i.e., more “base”). Using applicable statistics
that you compute from the dataset, conduct a hypothesis test to
determine whether there is evidence that average pH in Florida
lakes is different from the neutral value of 7. Use a statistical
significance (alpha) of 5%.
