What is the null hypothesis?

The value of the mean that is assumed to be true

What is the alternative hypothesis?

Tells about the value of the mean if the null hypthesis is shown to be wrong

How to get the actual significance level in a two-tailed test?

Add up the two critical values from the lower and upper region

If a number is in the critical region, is H₀ rejected or accepted?

Rejected

If the calculated probability is lower than the significance level, what is the conclusion?

Reject H₀

If the calculated probability is higher than the significance level, what is the conclusion?

Accept H₀

What is a one-tailed test?

H₁ : θ < m or θ > m

What is a two-tailed test?

H₁ : θ ≠
