The P-value is the area under the density curve of this chi-square distribution to the right of the value of the test statistic.
The final step of the chi-square test of significance is to determine if the value of the chi-square test statistic is large enough to reject the null hypothesis.
A chi-square critical value is a threshold for statistical significance for certain hypothesis tests and defines confidence intervals for certain parameters.
Chi-square critical values are calculated from chi-square distributions.
To calculate the expected numbers a constant multiplier for each sample is obtained by dividing the total of the sample by the grand total for both samples.
In table 8.1 for sample A this is 155/289 = 0.5363.
