Since the calculated p-value is above the significance level α = 0.05, the Null hypothesis H₀ can not be rejected. In other words, there is no trend in the series.

Since the calculated p-value is below the significance level α = 0.05, one must reject the Null hypothesis H₀ and accept the Alternative hypothesis H₁. In other words, there’s a trend in the series.
