I test it is significantly larger than 2 on 5%? | s*******1 发帖数: 146 | 2 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 | d*******1 发帖数: 293 | | d*******1 发帖数: 293 | | l*******r 发帖数: 407 | 5 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 |
