Suppose $\mu$= 80 and $\sigma$ = 20 for a population.In a sample where n = 100 is randomly taken, 95% of all possible sample means will fall above 76.08.

Question

The 95% confidence interval for the population mean is 76.08 ± 1.96 * (20/√100) = 76.08 ± 3.92, which means that 95% of all possible sample means will fall between 72.16 and 80.00. Since 76.08 is within this range, the statement is true.
