Part (a)

A parameter is a numerical characteristic of a population. The symbol $\mu$ represents the population mean, which is a parameter as it describes the entire population.

A statistic is a numerical characteristic of a sample. The symbol $\bar{x}$ represents the sample mean, which is a statistic as it is calculated from a sample of the population.

The symbol $\sigma$ represents the population standard deviation. Since it describes the entire population, it is a parameter.
