The probability value below which the Null Hypothesis (H₀) is rejected is also called the significance level (α)

Only the p-value approach can be used to determine if the Null Hypothesis (H₀) can be rejected.

With α=0.05, do we have enough empirical evidence to reject Null Hypothesis (H₀)?

With test statistics T =-4.60, we should reject the null hypothesis.

Data support the claim that the means are similar in the two groups.

Test statistics is T =1.22. So, there is sufficient evidence to reject the Null Hypothesis (H₀).
