"Critical region" redirects here. For the computer science notion of a "critical section", sometimes called a "critical region", see critical section.

A statistical hypothesis is a hypothesis that is testable on the basis of observing a process that is modeled via a set of random variables.[1] A statistical hypothesis test is a method of statistical inference. Commonly, two statistical data sets are compared, or a data set obtained by sampling is compared against a synthetic data set from an idealized model. A hypothesis is proposed for the statistical relationship between the two data sets, and this is compared as an alternative to an idealized null hypothesis that proposes no relationship between two data sets. The comparison is deemed statistically significant if the relationship between the data sets would be an unlikely realization of the null hypothesis according to a threshold probability—the significance level. Hypothesis tests are used in determining what outcomes of a study would lead to a rejection of the null hypothesis for a pre-specified level of significance. The process of distinguishing between the null hypothesis and the alternative hypothesis is aided by identifying two conceptual types of errors (type 1 & type 2), and by specifying parametric limits on e.g. how much type 1 error will be permitted.

An alternative framework for statistical hypothesis testing is to specify a set of statistical models, one for each candidate hypothesis, and then use model selection techniques to choose the most appropriate model.[2] The most common selection techniques are based on either Akaike information criterion or Bayes factor.

Statistical hypothesis testing is sometimes called confirmatory data analysis. It can be contrasted with exploratory data analysis, which may not have pre-specified hypotheses.

PLZ HELP…Identify a passage in the dialogue between Lizabeth's parents that helps convey their characters.
Ksenya-84 [330]

A passage in the dialogue between Lizabeth's parents that help convey their characters is

  • the scene where her father lamented for not having bought his wife a gift for twenty-two years.

The scene is a very touching one that elicits feelings of pity and grief for the poor condition of the family.

The man laments about not having bought anything for his wife for the past twenty-two years. He is sad and sobs like a child for the deep poverty they found themselves in.

The scene is heartbreaking for it communicates the helplessness of the man in a relatable way.

Even when his wife tries to comfort him by promising a used coat from Mr. Ellis, the man feels more embittered because they have to use the leftovers of the whites.

These emotions are believable for no one likes poverty or having to live at the mercy of others.
