Samples were collected from two ponds in the Bahamas to compare salinity values (in parts per thousand). Several samples were drawn at each site. Pond 1: 37.03, 37.01, 37.02, 37.32, 37.54, 37.36, 38.85 Pond 2: 39.21, 38.24, 38.51, 38.53, 38.71 Use a 0.05 significance level to test the claim that the two ponds have the same mean salinity value.
