A cell phone manufacturer would like to estimate the mean difference in battery lifespan for a phone in full-power versus power-saver mode. They randomly select eight phones and determine the battery lifespan, in hours, for each phone using each power mode. A 90% confidence interval for the true mean difference (low power battery life - full power battery life) in battery life is 5.42 hours to 6.71 hours. A journalist claims that battery lifespan is, on average, 5 hours longer when the phone is used under low-power mode as opposed to full-power mode. Is this claim supported by the 90% confidence interval? Yes, 5 is a plausible value in the 90% confidence interval. No, 5 is not a plausible value in the 90% confidence interval. No, 0 is not a plausible value in the 90% confidence interval. Yes, 0 is not a plausible value in the 90% confidence interval
