WebGoodness of fit test: Calculate p-value To get a p-value, calculate the area under the chi-squared curve to the right of 1.397 Using JMP, this area is 0.703. If the null hypothesis … WebJan 24, 2024 · The chi-square statistic of 235.42 that we calculated corresponds to a particular location on a chi-square distribution with five degrees of freedom. We now need a p-value, to determines the probability of obtaining a test statistic at least as extreme as 235.42 while assuming that the null hypothesis is true.

WebWe see that the calculated value of the Chi-squared goodness of fit statistic is 27.306905068684152 and its p-value is 4.9704641133403614e-05 which is much smaller than alpha=0.05. Thus we conclude that Null Hypothesis H0 that NUMBIDS is Poisson distributed can be resolutely REJECTED at 95% (indeed even at 9.99%) confidence level.
