nment sample survey plans to sure the mean total cholesterol level of an SRS of men aged 20 to 34. The researc will report the mean x from their sample as an estimate of the mean total cholesterol level μ in this population. Explain to someone who knows no statistics what it means to say that is an "unbiased" estimator of μ. The sample mean is systematically higher than or lower than μ. is not The sample result x is an unoscu estimator of the population truthμ 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.

© Macmillan Learning A government sample survey plans to measure the mean total cholesterol level of an SRS of men aged 20 to 34. The researchers will report the mean x from their sample as an estimate of the mean total cholesterol level μ in this population. Explain to someone who knows no statistics what it means to say that x is an "unbiased" estimator of μ. 80 The sample mean is 易 is not The sample result x is an unoasca estimator of the population truth μ no matter what size SRS the study uses. systematically higher than or lower than u. Explain to someone who knows no statistics why a large sample gives more trustworthy results than a small sample. O With a large sample, x is more likely to be close to μ, because with a larger sample comes less information and therefore more uncertainty. O With a large sample, x is more likely to be close to μ, because with a larger sample comes more information and therefore less uncertainty. Q O With a large sample, x is more likely to be further away from μ, because with a larger sample comes more information and therefore less uncertainty. F5 With a large sample, x is more likely to be further away from μ, because with a larger sample comes less information and therefore more uncertainty. MacBook Air F6 K F7 DII F8 F9 F10 ที F11
