• C)A lower-than-normal volume of urine which was more concentrated than the blood (hypertonic)would be produced.
• D)A greater-than-normal volume of urine equal in concentration to the blood (isotonic)would be produceD.
• E)A greater-than-normal volume of urine that was more concentrated than the blood (hypertonic)would be produced.

Definitions:

Consistency

refers to the property of an estimator in which, as the sample size increases, it converges in probability to the parameter it estimates.

Interval Estimator

An interval estimator provides a range of values, defined by an upper and lower bound, that is likely to contain the population parameter of interest.

Sample Mean

The average of a subset of numbers from a larger set, representing the central tendency of that subset.

Consistent Estimator
