We are 95% confident that the interval from $113.05 to $136.95 captures u = the true mean purchase total for all customers.
Is it plausible that the true mean purchase total for all customers may be $140?
Yes, this is a plausible value for the population mean because $140 is within the 95% confidence interval.
O No, this is not a plausible value for the population mean because $140 is within the 95% confidence interval.
O Yes, this is a plausible value for the population mean because $140 is only a little bit above the upper boundary of
the 95% confidence interval.
No, this is not a plausible value for the population mean because $140 is not within the 95% confidence interval.
