We can measure how good an estimator is by considering the (a) and the variance of the estimator.
what is the (a)?
Homework Answers
Answer : (a) is mean.
To know about the goodness of estimator we need to know about the distribution of the estimator. And to do that we need to know about the mean and variance of the estimator.

Mean and variance
Answer can be one or multiple
If an estimator is unbiased, then its value is always the value of the parameter, its expected value is always the value of the parameter, O it variance is the same as the variance of the parameter.

When we use the composite-good convention, what do we mean by a composite good and how do we measure it? What is the slope of the budget line? What is the slope of an indifference curve? Does the consumer equilibrium involve an equality between MRS and a price ratio? Was trying to get the breakdown for this problem as far how you got the answer. Thanks!
