The null hypothesis would be: Fourth‐graders in Elmwood School perform the same in math as fourth‐graders in Lancaster School. In notation:H0: μ1= μ2 or:H0: μ1– μ2= 0 Some research hypotheses are more specific than that, predicting not only a difference but a difference in a pa...
100 of a certain solution, or 100 P 100 different solutions The computer could verify some solution, but if that solution is not 100 P # certain or 100 P Null, then the P=NP hypothesis is disproved as P NULL and P # certain do not agree with solutions of 100P different solutions. ...
