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. Determine whether the following are examples of estimators, estimates or neither. A. . estimator estimator estimate neither B. . estimate estimate neither estimator C. . neither neither estimator estimate D. . estimate neither estimate estimator E. . estimate estimate neither estimator
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.
Firstly, you change it to miles per second and then to feet 102miles per hour(60×60s) 102 per 120s Divide 102÷120 =0.85miles per second Convert to feet =4488 feet per second
