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, 37.45, 36.75, 37.54, 37.71, 37.02, 37.32 Pond 2: 38.89, 39.05, 38.51, 38.53, 38.71 Use a 2% significance level to test the claim that the two ponds have the same mean salinity value. Assume that nothing is known about the population distribution of salinities. (a) Enter the rank values in the same order as in the original sample. The rank values for Pond 1 are: The rank values for Pond 2 are: (b) The test statistic is: . (c) The test critical value is: . (d) The conclusion is
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, 37.45, 36.75, 37.54, 37.71, 37.02, 37.32
Pond 2: 38.89, 39.05, 38.51, 38.53, 38.71
Use a 2% significance level to test the claim that the two ponds have the same mean salinity value. Assume that nothing is known about the population distribution of salinities.
(a) Enter the rank values in the same order as in the original sample.
The rank values for Pond 1 are:
The rank values for Pond 2 are:
(b) The test statistic is: .
(c) The test critical value is: .
(d) The conclusion is
A. There is not sufficient evidence to indicate that the two ponds have different distributions of salinity values.
B. There is sufficient evidence to indicate that the two ponds have different distributions of salinity values.
