is an example of a point estimate.

should always be centered on the population mean (µ).

provides less information than the corresponding hypothesis test.

All of the options listed above correctly complete the sentence.

None of the options listed above correctly complete the sentence.

Answer 1

Confidence interval is not point estimation as it does not give a single value for the estimator,but provides an interval. Hence, confidence interval is not an example of point estimation.

Confidence interval need not always be centred around the population mean. According to the need and requirement of study the confidence interval can be centered around any other parameter as well like variance, etc.

Confidence intervals are not less informative than the corresponding hypothesis test. Infact it is more informative about the significance of parameter to be tested.

Hence, none of the options above correctly completes the sentence.
