The critical value $\chi^2$ can be found using a $\chi^2$ distribution table or calculator, corresponding to a confidence level of 99% and degrees of freedom (df). The degrees of freedom for a sample size of 19 is 18 (df = n - 1). Looking up the critical value for 99% confidence and 18 degrees of freedom gives us 37.156.
