Interpret the results at = 0.05. O We conclude that the mean difference differs from zero. OWe cannot conclude that the mean difference differs from zero. OWe conclude that population mean 2 is greater than population mean 1. OWe cannot conclude that population mean 2 is greater than population mean 1.
