s Office conducted a study of how students' involvement into social networks = X measured in hours per week affects their test scores = Y (in a 100-point scale). They assumed all conditions required for this model and used a sample of n = 20 students. As a result, they derived the fitted line equation in the form: Y = 70-2.85 X with the standard error for the estimated slope equal to SE (b) = = 1.5 At the significance level a = 0.05, do they have enough evidence that social networking has ANY impact (positive or negative) on students' test performance? 1. Specify the critical value (or values) required in this case. 2. Formulate Rejection Rule 3. Evaluate the Test Statistic
