Webnull hypothesis that the medians of the two groups are the same. The normal approximation used above is only an approximation to the p value and it is possible to construct the exact p value. This is given in the next row and we see that the exact p value is .309 whilst the asymptotic p value is .309. WebPRATT HYPOTHESIS PRATT MODEL The Pratt model where different topographic heights are accommodated by lateral changes in rock density. In essence, this says that areas of the Earth of lesser density, such as mountain ranges, project higher above sea level than do those of greater density. raytheon quarterly dividend
