A government sample survey plans to measure the LDL (bad) cholesterol level of an SRS of men aged 20 to 34. The researchers will report the mean $\bar{x}$ from their sample as an estimate of the mean LDL cholesterol level $\mu$ in this population. Step 1 Explain to someone who knows no statistics what it means to say that the sample mean $\bar{x}$ is an unbiased estimator of $\mu$. The sample mean $\bar{x}$ is _ systematically higher than or lower than $\mu$. Step 2 The sample result $\bar{x}$ is an unbiased estimator of the population truth $\mu$ no matter what size SRS the study uses. Explain to someone who knows no statistics why a large sample gives more trustworthy results than a small sample. With a large sample, $\bar{x}$ is more likely to be
