Test Statistic
t-Distribution (df = 14)
Classical Approach
Critical Region: t < -2.145 or t > 2.145
t₀ = 3.0258 is in rejection region
P-Value Approach
P-value = 0.0091
P-value < α = 0.05
Reject H₀
At the α = 0.05 level, there is sufficient evidence to conclude that the mean difference is different from 0.
