Consider the data below.  Three random samples in different cities were selected.  Water use per household per day were measured.  Test the claim that the samples come from populations with the same mean.  Assume all requirements have been met.  Use a 5% level of significance. Identify the tail of the test.        Find the P-value.       Will the null hypothesis be rejected?      Do the populations appear to have the same mean?        City 1 City 2 City 3 56 57 45 60 65 45 56 54 45 41 48 44 45 56 66 66 54 61 58 45
