A researcher is 95% confident that the interval from 5.2 hours to 7.8 hours captures y = the true mean amount of time it takes to fully charge a battery pack,
Is it plausible that the true mean number of hours to charge all battery packs of this type may be 5?
No, this is not a plausible value for the population mean, because 5 is within the 95% confidence interval.
No, this is not a plausible value for the population mean, because 5 is not within the 95% confidence interval.
Yes, this is a plausible value for the population mean, because 5 is within the 95% confidence interval.
Yes, this is a plausible value for the population mean, because the lower bound of the confidence interval, 5.2
greater than 5
