Use α = 0.05, one-tailed, and a critical value of 0.669. a) Calculate the Pearson’s Correlation and show your work. Numerator and work: [CorrNum] Denominator and work: [CorrDem] Correlation coefficient and work: [CorrCoeff] b) Make a decision about the null hypothesis: [CorrDecision] Interpret the results of this experiment: [CorrInterpret] Display the statistical results of your correlation in APA format. Make sure you include effect size, if appropriate. [CorrAPAStats] c) Find the regression equation for predicting someone’s Self-Handicapping score (Y) from their Self-Esteem score. Show your work. SP = 27, SSx = 29, SSy = 32 Mx = 7, My = 11 *note: these values are NOT the same values as the table you calculated beta and work: [beta] y-intercept and work: [y-intercept] d) Does the regression equation you created in part c account for a significant portion of the variance in Self-Handicapping? Use α = 0.05, and critical value of 6.61 to evaluate the F-ratio. SStotal = 34, SSresidual = 9.8 n = 7 Mx = 7, My = 11 F-ratio numerator and work: [RegNum] F-ratio denominator and work: [RegDem] Plain English interpretation: [RegInterpret] Display the statistical results of your regression in APA format. You do not need to include effect size. [RegAPAStats]
