Application Exercise: A medical researcher wants to begin a clinical trial that involves systolic blood pressure (SBP) and cadmium (Cd) levels. However, before starting the study, the researcher wants to confirm that higher SPB is associated with lower Cd levels. Below are the SBP and cd measurements for a sample a participants. What can the researcher conclude with an a of 0.05? cd SBP 55.9 169 55.7 161 55.7 115 55.5 113 55.9 182 55.8 126 55.8 179 55,5 127 55.7 148 55.8 160 55.6 140 a) What is the appropriate statistic? Independent Samples t-test Compute the statistic selected in a): b) Obtain/compute the appropriate values to make a decision about Ho. Critical Value - ; Test Statistic = Decision: ---Select-- c) Compute the corresponding effect size(s) and indicate magnitude(s). If not appropriate, input and/or select "na" below. Effect Size = Magnitude: --Select- d) Make an interpretation based on the results. There was a significant positive relationship between systolic blood pressure and cadmium levels. There was a significant negative relationship between systolic blood pressure and cadmium levels. There was no significant relationship between systolic blood pressure and cadmium levels
