mean of population 37321614 994 2475 mean of the samples me

mean of population = 37+32+16+14 =99/4 =24.75

mean of the samples means = 37+24+34.5+23+32+16+26.5+15+25.5+14 = 247.5/10=24.75

The mean of the population is equal to the mean of the sample mean

C - Do the sample means target the value of the population mean? In general, do sample means make good estimates of population means? Why or why not?

The sample means “do target or do not target” the population mean. In general, sample means “do or do not” make good estimates of population means because the mean is “a bias or unbiased” estimator?

Do target or do not target?

do or do not?

Bias or unbiased?

Solution

Yes, sample means target population means, in general sample means do make good estimates of pop. means, because the mean is unbiased estimator
