A line graph displays monthly average temperature with a shaded 95% confidence interval band. At month 6, the observed temperature (line) is 22°C, with confidence band [20°C, 24°C]. Which statements are CORRECT?
(I) 95% of individual days in month 6 have temperatures between 20–24°C.
(II) We can be 95% confident that the true population mean temperature is between 20–24°C.
(III) If we repeat this study many times, approximately 95% of the confidence intervals will contain the true mean.
