A degree of confidence attached to an interval estimate is called 1.. A rule that calculates an estimate of a parameter of interest is called 2..
The size of the error of estimation should not exceed the 3..
A single computed value to represent an unknown parameter is called 4..
An interval estimate with an attached level of confidence is called 5..
An estimator is 6. if the mean of its sampling distribution is equal to the true value of the parameter.
The best point estimator for a parameter of interest must be unbiased and of 7. variance among all other 8. involves the construction of a range of possible values that estimates an unknown parameter.
The 9. is the best point estimator for the population mean.
The 10. must be increased to obtain a narrow interval estimate with a high confidence level.
