Finding Critical Values of χ2 Repeat Exercise 19 using this approximation (with k and z as described in Exercise 19):
19. Finding Critical Values of χ2 For large numbers of degrees of freedom, we can approximate critical values of χ2 as follows:
Here k is the number of degrees of freedom and z is the critical value(s) found from technology or Table A-2. In Exercise 12 “Spoken Words” we have df = 55, so Table A-4 does not list an exact critical value. If we want to approximate a critical value of χ2 in the right-tailed hypothesis test with α = 0.01 and a
