Based on answers to a questionnaire, the researchers measured two variables for each subject: assertiveness score (x) and leadership ability score (y). A quadratic regression model was fit to the data with the results below. Complete parts a through c. Independent Variable B Estimate t-value p-value x 0.43 2.53 0.01 2 - 0.206 - 3.85 0 OB. Ho: B1 = 0 Ha : By = 0 Ha: By > 0 O C. Ho: B2 = 0 OD. Ho: B2 0 c. Use the reported results to conduct the test, part b. Give your conclusion (at a = 0.10) in the words of the problem. What is the p-value for the test? O 0.005 O
