P value and q value
WebAll p on the interval [1,5] only. p=0 only p=1 and p=5 only. Question: Let p be a constant. For what value(s) of p is the integral ∫15x−p1dx improper? (i.e. for what p value(s) would we need to use the "Improper Integrals - Type 2 " techniques to solve?) This integral is never improper. The integral is improper for all p on (−∞,∞). WebIf we take unknown compound 1723 as an example, we see that it has a p-value of 0.0101 and a q-value of 0.0172. Recall that a p-value of 0.0101 implies a 1.01% chance of false …
