g X, Y, and Z are all estimators of the same parameter. X and Y are unbiased estimators, while Z is biased. Also, the variance of X is larger than the variance of Y which is larger than the variance of Z. What can you conclude about in this case about the relative efficiency of these estimators

Step-by-step explanation:

Going by variance size, Estimator Z is relatively more efficient than Estimator Y and Estimator Y is relatively more efficient than Estimator X.

By bias, estimators X and Y would have been preferred to estimator Z but if estimator Z has small bias, it should be more efficient than X and Y, especially as it has the smallest variation (variance) from the true value of the variable.

step-by-step explanation:

a rhombus is a parallelogram enjoying his symmetry.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
