A researcher is 95% confident that the interval from 5.8 minutes to 9.3 minutes captures u = the true mean amount of time it takes to pump a full tank of gas in a certain type of SUV,
Is it plausible that the true mean number of minutes to fully fill a tank of gas for this type of SUV may be 9?
No, this is not a plausible value for the population mean, because 9 is within the 95% confidence interval.
No, this is not a plausible value for the population mean, because 9 is below the upper bound of the 95%
confidence interval
Yes, this is a plausible value for the population mean, because 9 is within the 95% confidence interval.
Yes, this is a plausible value for the population mean, because 9 is not within the 95% confidence interval.
