## 8.2: Large Sample Tests for a Population Mean

This implies that the statistic. Since the sample is large the resulting test statistic still has a distribution that is approximately standard normal. It is hoped that a newly developed pain reliever will more quickly produce perceptible reduction in pain to patients after minor surgeries than a standard pain reliever. We perform the test of hypotheses using the five-step procedure given at the end of Section 8.

## Estimation of other parameters

The most fundamental point and interval estimation process involves the estimation of a population mean. When the sample mean is used as a point estimate of the population mean, some error can be expected owing to the fact that a sample, or subset of the population, is used to compute the point estimate. Interval estimation incorporates a probability statement about the magnitude of the sampling error. The standard deviation of a sampling distribution is called the standard error. As a matter of practice, statisticians usually consider samples of size 30 or more to be large. The quantity 1. By changing the constant from 1.

### 8.2: Large Sample Tests for a Population Mean

We present conditions for obtaining cosistency and asymptotic normality of a very general class of estimators extremum estimators. Consistent asymptotic variance estimators are given to enable approximation of the asymptotic distribution. Asymptotic efficiency is another desirable property then considered. Throughout the chapter, the general results are also specialized to common econometric estimators e.

#### Estimation procedures for two populations

Часы показывали два часа с минутами по местному времени. Возле главного здания аэровокзала Беккер въехал на тротуар и соскочил с мотоцикла, когда тот еще двигался. Машина упала на бок и замерла. На затекших ногах Беккер прошел через вращающуюся дверь. Больше никаких мотоциклов, пообещал он. Ярко освещенное помещение аэровокзала сияло стерильной чистотой. Здесь не было ни души, если не считать уборщицы, драившей пол.
