To calculate the standard error of the slope coefficient, you can use the formula:
se(b©û) = ¢²(y − ŷ)©÷ / ¢²x©÷
We are given that ¢²(y − ŷ)©÷ = 35,168.50 and ¢²x©÷ = 18,476. Plugging these values into the formula, we get:
se(b©û) = 35,168.50 / 18,476
Calculating this, we find that:
se(b©û) ≈ 1.902
So, the correct option is not provided in the given choices. Please double-check the calculations or the provided data to find the correct answer.
