O The results are statistically insignificant at a = 0.01, so there is insufficient evidence to conclude that the population mean time in the shower for the poor is less than the population mean time in the shower for the rich. The results are statistically significant at a = 0.01, so there is sufficient evidence to conclude that the mean time in the shower for the ten poor people that were surveyed is less than the mean time in the shower for the thirteen rich people that were surveyed. The results are statistically insignificant at a = 0.01, so there is statistically significant evidence to conclude that the population mean time in the shower for the poor is equal to the population mean time in the shower for the rich. O The results are statistically significant at a = 0.01, so there is sufficient evidence to conclude that the population mean time in the shower for the poor is less than the population mean time in the shower for the rich.
