Expert Solution

Step 1

Hypothesis is a statement regarding the population parameter . Hypothesis testing is used to make statistical decisions using experimental data.

Null hypothesis (H₀ ): Null hypothesis is a statistical hypothesis that assumes that the observation is due to a chance factor. It is a "no difference " statement regarding the population parameter . Which consider ( $\geq, =, \leq$ ) signs .

Alternative hypothesis (H₁ ): Contrary to the null hypothesis, the alternative hypothesis shows that observations are the result of a real effect. It is is difference between two parameters . Which consider (> , = , < ) signs

One-tailed test: When the given statistical hypothesis is one value , it is called the one-tailed test.

Two-tailed test: When the given statistics hypothesis assumes a less than (<) or greater than (>) value, it is called the two-tailed test.
