A manufacturer of televisions claims that the average life for a certain model is 7 years. A consumer organization would like to test the manufacturer's claim to ensure that the average life is not actually less than 7 years. Which pair of hypotheses should be used?

Null hypotheses

Explanation:

The six most common forms of hypotheses are:

Simple Hypothesis Complex Hypothesis Empirical Hypothesis Null Hypothesis Alternative Hypothesis Logical Hypothesis Statistical Hypothesis

A simple hypothesis is a prediction of the relationship between two variables: the independent variable and the dependent variable.

A complex hypothesis examines the relationship between two or more independent variables and two or more dependent variables.

A null hypothesis (H0) exists when a researcher believes there is no relationship between the two variables, or there is a lack of information to state a scientific hypothesis. This is something to attempt to disprove or discredit.

A logical hypothesis is a proposed explanation possessing limited evidence. Generally, you want to turn a logical hypothesis into an empirical hypothesis, putting your theories or postulations to the test.

An empirical hypothesis, or working hypothesis, comes to life when a theory is being put to the test, using observation and experiment. It's no longer just an idea or notion. It's actually going through some trial and error, and perhaps changing around those independent variables.

A statistical hypothesis is an examination of a portion of a population.
