A researcher is 95% confident that the interval from 19.7 posts to 27.3 posts captures u = the true mean amount
of posts high school students make daily on social media.
Is there evidence that the true mean number of posts high school students make is less than 27?
O No. There is not evidence for the population mean to be less than 27, because 27 is within the 95% confidence
interval.
O No. There is not evidence for the population mean be less than 27, because there are values greater than 27
within the 95% confidence interval.
O Yes, there is evidence for the population mean to be less than 27, because 27 is within the 95% confidence
interval.
Yes, there is evidence for the population mean to be less than 27, because 27 is closer to the upper bound of the
95% confidence interval than the lower bound.
