Q 25- 25- 25- 25 Q Residuals 0- Residual Residuals Residuals -25 + TTT .25- 0 25 25+ 25 2.5 2.5 Normal Scores Normal Scores Normal Scores Normal Scores Evaluate the plots to determine if a linear regression is appropriate. Choose the correct answer below. O A. The plot of the residuals against x shows no pattern, which is a possible violation of the Independence Assumption. The Normal probability plot indicates that the Normal Probability Assumption is violated. B. The plot of the residuals against x tends to spread out as x increases, which is a possible violation of the Equal Variance Assumption. The Normal probability plot indicates that the Normal Population Assumption is satisfied. C. The plot of the residuals against x tends to cluster as x increases, which is a possible violation of the Linearity Condition. The Normal probability plot indicates that the Normal Population Assumption is satisfied. O D. The plot of the residuals against x shows no pattern, which satisfies the conditions for linear regression. The Normal probability plot indicates that the Normal Probability Assumption is violated. c) Test an appropriate hypothesis using a = 0.05 to determine if the association is significant. Choose the correct null and alternative hypotheses. O A. Ho: Po = 0 HA: PO # 0 OB. Ho: Po = B1 HA: Po # B1 O C. Ho: Bo = B, = 0 HA: B1 # 0 or B1 # 0 D. Ho: B, = 0 HA: B1 2 0 Determine the test statistic. Round to two decimal places as needed.)
