Combining proportions
WebThe overall sample proportion is: p ^ = 41 + 351 195 + 605 = 392 800 = 0.49. That implies then that the test statistic for testing: H 0: p 1 = p 2 versus H 0: p 1 ≠ p 2. is: Z = ( 0.58 − 0.21) − 0 0.49 ( 0.51) ( 1 195 + 1 605) = … Web7. this is something that often comes up in both Physics and Mathematics, in my A Levels. Here is the crux of the problem. So, you have something like this : A ∝ B which means that (1) A = k B. Fine, then you get something like : A ∝ L 2 which means that (2) A = k ′ L 2. Okay, so from ( 1) and ( 2) that they derive :
