46.

A confidence interval for a mean age of 72 years is reported as 95% CI = (65 to 89). You would interpret this confidence interval to mean that:

the confidence is 95% that the sample mean lies between 65 and 89 years of age.

the confidence is 95% that the population mean lies between 65 and 89 years of age.

the confidence is 95% that the population mean lies below 65 and above 89 years of age.

the confidence is 95% that the sample mean lies below 65 and above 89 years of age.

the confidence is 95% that the sample mean lies between 65 and 89 years of age.

the confidence is 95% that the population mean lies between 65 and 89 years of age.

the confidence is 95% that the population mean lies below 65 and above 89 years of age.

the confidence is 95% that the sample mean lies below 65 and above 89 years of age.

Answer is "the confidence is 95%that the population mean lies between 65 and 89 years of age.

Because a confidence interval measures the probability that the population parameters fall between two sets values.
