Q3. Test the hypothesis that higher ERIratio predicts lower sIgA concentrations. (.5) In apaformat for the results of this test in terms of effect size and F test.

Q4. Produce a residual plot of the analysis in Q3. Report on your visual assessment of the presence of outliers (i.e., influential cases) and the criteria you have used in this visual assessment

Q.5 Next, perform a statistical residual analysis of the relationship to remove outliers. Report on the revised regression without these outliers, in terms of effect size and F test in apaformat sentencing... Also explain how ERIratio predicted sIgA better, or worse, without these outliers.

Could you please state, steps used on SPSS.
