We can make useful statements about the population to inform business decision-making.

We can be 100% sure of our results

Results will not vary depending on the particular sample 

None of the answers is true

A desirable property of point estimators according to which the expected value of the statistic equals the parameter.

A desirable property of point estimators according to which the bias decreases when the sample size increases.

None of the answers is correct.

A desirable property of point estimators according to which the estimator has the smallest variance possible.

The sample mean must approach the population mean as the size of the sample grows.

None is true

The population mean must approach the sample mean as the size of the sample grows.

The population mean is the natural estimator of the sample mean.

How confident we are that the parameter, population mean, is estimated accurately.

All are true

How accurate we believe our guess for the parameter is, based on the variability of the estimate and how confident we are that the procedure will catch the true population mean.

The variability of the estimate based solely on the characteristics of the parameter.
