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: 37.32, 37.71, 37.01, 37.36, 37.02, 37.54, 36.72 pond 2: 38.24, 38.51, 38.66, 39.05, 39.04 use a 0.05 significance level to test the claim that the two ponds have the same mean salinity value. (a) the test statistic is . (b) the conclusion is a. there is sufficient evidence to indicate that the two ponds have different salinity values. b. there is not sufficient evidence to indicate that the two ponds have different salinity values. (c) we should a. remove the largest and smallest values from the larger data set and only test equal size samples. b. check to see if the data appear close to normal since the sum of the sample sizes is less than 15. c. not take the results too seriously since neither sample is big enough to be meaningful. d. all of the above.
