Tristan has completed his STAT 1342 course. He intends to build a simple linear regression model control variable (X) as number of hours per week for his preparations and (Y) as the weekly perform measured in a 100-point scale. There were totally n = 13 records combining his ten homework score three exam grades. The model built by Tristan was: Ý = 10 +7. X with the standard error of estimated slope equal to SE = SE [b] = 2.5 1. At the significance level, a = 0.01, is there sufficient evidence that X positively impacts Y • Evaluate Test Statistic Specify critical value (or values) for this procedure • State the Rejection Rule • Formulate your decision 2. Estimate the population slope (= B) with confidence level, C = 0.99 • Specify critical value (or values) for this procedure • Evaluate UCL and LCL Solution
