To determine

Test the hypothesis.

Explanation of Solution

The null hypothesis (H₀) is ${\text{ρ}}_{\text{S}}=\text{0}$, and the alternate hypothesis (H₁) is ${\text{ρ}}_{\text{S}}>\text{0}$.

The Spearman rank correlation output is obtained using the statistical software. The result is given below:

The z value is 9.64 and the p value is 0. Since the p value is equal to 0, the alternate hypothesis is accepted.
