A study examining glucose levels in a group of individuals taking antipsychotics reports a mean value of 7 mmol/L. The sample size is 9, and the standard deviation of the sample is 6 mmol/L. The standard error of the mean is 2 mmol/L. What is the closest estimate for the correct range of the 95% confidence interval? Additionally, suppose the study was conducted on a population of individuals aged 65 and above.
