Thus, the final conclusion is that ...The results are statistically significant at a = 0.10, so there is sufficient evidence to concludethat the mean time in the shower for the ten poor people that were surveyed is less than themean time in the shower for the eleven rich people that were surveyed.O The results are statistically insignificant at a = 0.10, so there is statistically significant evidenceto conclude that the population mean time in the shower for the poor is equal to the populationmean time in the shower for the rich.The results are statistically significant at a = 0.10, so there is sufficient evidence to concludethat the population mean time in the shower for the poor is less than the population mean timein the shower for the rich.O The results are statistically insignificant at a = 0.10, so there is insufficient evidence to concludethat the population mean time in the shower for the poor is less than the population mean timein the shower for the rich.

Question Help Instructor-created question Sham Magnet H1 Researchers conducted a study to determine whether magnets can affect back pain. The results are shown in the table for the treatment (with magnets) group and the sham (or placebo) group. The results are a measure of reduction in back pain. Assume that the two samples H are independent simple random samples selected from normally distributed populations, and do not assume that the population standard deviations are equal.
