FACT OR BLUFF

The notation 𝜇 and 𝜎 are sample values.

• FACT

• BLUFF

The alternative hypothesis is a statement that there is no significance difference between the two given properties.

• FACT

• BLUFF

In the given, 𝐻𝑜: 𝜇 = 21.5 and 𝐻𝑎: 𝜇 > 21.5 show a one-tailed test since it shows direction of the distribution.

• FACT

• BLUFF

The rejection region for a hypothesis test is also called the critical region.

• FACT

• BLUFF

The two types of significance test are one-tailed and two-tailed test.

• FACT

• BLUFF

The level of significance refers to the degree of significance in which we reject or fail to reject the null hypothesis.

• FACT

• BLUFF

We don’t need to set the level of the significance because we can get 100% accuracy level in testing hypothesis.

• FACT

• BLUFF

A two-tailed test shows that the null hypothesis may be rejected when the test value is on the critical region on either side of the distribution.

• FACT

• BLUFF

Hypothesis testing is basically testing an assumption that we make about the population parameter.

• FACT

• BLUFF

In a two-tailed test, the null hypothesis should not be rejected when the test value is on either of the two critical regions.
