Answer 1

For n - 2 = 10 degrees of freedom, we have from t distribution tables here:
P( t₁₀ < 2.228) = 0.975

Therefore, due to symmetry, we have here:
P(-2.228 < t₁₀ < 2.228) = 0.95

Therefore the confidence interval here is obtained as:

$\beta_3 \pm t^*SE$

032654298*10808

$0.33 \pm 0.19$

Therefore B is the correct answer here.
