if normal distribution with mean =1 and std=2, then for a value =3, how can
I test it is significantly larger than 2 on 5%?

P(X>3)=dnorm(3, mean=1, sd=2)=0.121;
P(X>2)=dnorm(2, mean=1, sd=2)=0.176
P(X>2)-P(X>3)=0.055

Why use P(X>2)-P(X>3)?

From the information your provided, there should be no statistical
difference between 3 and 2, because they are only 2 samples from that normal
distribution. The only difference is that two numbers have different
probabilities
