A strength аnd cоnditiоning speciаlist runs а Spearman's rank cоrrelation in R between athlete wellness survey rankings and practice performance rankings across a 12-week season and receives an output of ρ = 0.71 with a p-value of 0.018. A colleague argues that because the p-value is below 0.05, the specialist can now use wellness rankings to accurately predict individual practice performance on any given day. Which of the following best addresses this claim?
