A study is conducted involving 12 infants to investigate the association between gestational age at birth, measured in weeks, and birth weight, measured in grams. Use Spearman rho to test the hypothesis at 5% level of significance. What is the value of ΣD2? What is the absolute calculated ρ(rho) value? Using the tabulated rho value ρρtabtab = 0.587, what is the decision? do we accept Ho or reject Ho?
