I'm a bit stuck on how to calculate the probability in part b from the linear regression parameters.

I tried plugging the parameter values into the linear regression model: Y =β0+β1X+ε, ε∼N(0,σ)

So P(Y=y| X=40) = 2.85 + 0.07 * 40 + 1^2

P(Y=y|X=40) = 5.65

But I don't think this is the value I want. Any ideas where I'm going wrong?
