please I need help solving this practice question

08(16). The lifetime of one virus is supposed to be longer under lower temperature environment. We collected a sample about temperatures and lifetime. see data below. temperatures (x): 0, 3, 1, 1, -1, 2 lifetime in hours (y): 3.2, 1.4, 2.5, 2.0, 3.6, 2.8 2 x, = 6, 2y,- = 15.5, 2w.- = 10.7, 22:? =16, 2 y? = 43.25. 1.(4) Find the estimated regression line. 2.(2) Predict the true mean lifetime for temperature of 1.5. 3.(5) Complete the ANOVA table for this regression model, and do an F test for the model significance. or = 0.05. 4.(5) Conduct a t test Ho : [51 = 0, H1 : 1 75 0 for the regression. Solve by reject region method. a = 0.05
