The Parthenon in Greece uses the golden ratio as well as the Pyramids of Giza
I think, the estimate is a numerical value, wile the estimator is a function or operator, which can be generate more estimates according to some factors. For example (xbar) is estimator for (meu), which can be various when the sample size in various, the value that will be produced is an (estimate), but (xbar) is estimator.

Estimator is the correct spelling.
In statistics, an efficient estimator is an estimator that estimates the quantity of interest in some "best possible" manner
what is another name for estimator
Answer this question Critria of good estimator

The best estimator of the population mean is the sample mean. It is unbiased and efficient, making it a reliable estimator when looking to estimate the population mean from a sample.

There are four main properties associated with a "good" estimator. These are: 1) Unbiasedness: the expected value of the estimator (or the mean of the estimator) is simply the figure being estimated. In statistical terms, E(estimate of Y) = Y. 2) Consistency: the estimator converges in probability with the estimated figure. In other words, as the sample size approaches the population size, the estimator gets closer and closer to the estimated. 3) Efficiency: The estimator has a low variance, usually relative to other estimators, which is called relative efficiency. Otherwise, the variance of the estimator is minimized. 4) Robustness: The mean-squared errors of the estimator are minimized relative to other estimators.

The majority of the major car manufacturers have a car payment estimator on their web sites. Most banking institutions may have this function as well. The payment is just an estimator.
The proof that demonstrates the unbiased estimator of variance involves showing that the expected value of the estimator equals the true variance of the population. This is typically done through mathematical calculations and statistical principles to ensure that the estimator provides an accurate and unbiased estimate of the variance.
It depends what type of screen you're watching it on ! A 'standard' TV set uses 4:3 ratio. A wide-screen model uses 16:9 ratio.
