What is the difference between an estimator and an ​estimate? A. An estimator is a function of a sample of data to be drawn rand

omly from a population whereas an estimate is the numerical value of the estimator when it is actually computed using data from a specific sample. B. Both an estimator and an estimate are functions of a sample of data to be drawn randomly from a population. C. Both an estimator and an estimate are numerical values computed using data from a specific sample. D. An estimate is a function of a sample of data to be drawn randomly from a population whereas an estimator is the numerical value of the estimator when it is actually computed using data from a specific sample.

Answer: A. An estimator is a function of a sample of data to be drawn randomly from a population whereas an estimate is the numerical value of the estimator when it is actually computed using data from a specific sample.

Step-by-step explanation: The estimator is simply used to on obtaining an estimate from a sample of data. Thus, the estimator may be described as a function built according to a set of defined rules and statistical component which is used to infer a numerical value of an estimate from a given sample of observed data. Hence, the estimator may be regarded as the function or rules adopted in our quest to obtain an estimate for a given population from a sample of data. The value obtained for the mean of a sample of data is called an estimate of the population, the rules for Deriving the estimated value is called the estimator.

explain why the exponents cannot be addded in the proududct 12 to the third power 11 to the third power
Oksi-84 [34.3K]
12 ^3  and 11^3   haven't got the same base  so the rules of exponents do not apply.

Bases have to be the same:-  for example 12^3 * 12*3  = 12 ^(3+3)  = 12^6

If the floor of a square office is 225 square units, what is the perimeter of the office?
Makovka662 [10]
Square have 4 equal sides length = a

A = 255 
A = a^2

255 = a^2   |sqrt
15 = a

P = 4a 
P = 4*15 = 60
