WebStep Five: Make a Statistical Decision (via the Decision Rule) With α = 0.05α = 0.05 (area in blue) and df = 15df = 15, the critical value is t ∗ = 1.753 t∗ = 1.753. Hence, the decision rule is to reject H0H 0 when the value of the computed test statistic tt exceeds critical value t ∗ t∗, or reject H0H 0 if t > t ∗ t >t∗. WebI.
