Question

a)alpha =0.05, r=3, c=7.                                    b)alpha = 0.01 , r= 7, c=4.                                 c) alpha =0.01, r=7, c=3.                                    d) alpha= 0.01, r=4, c=3.                                     e) alpha= 0.01, r=3, c=5.                                    1) Determine the upper-tail critical value of the test statistic after calculating the degrees of freedom using the values given in the above problem statements for (a through e) round the critical value to the three decimal places.

Explanation / Answer

Upper-tail critical values of chi-square distribution with degrees of freedom

a] alpha =0.05, r=3, c=7           df = (r-1)(c-1) = 12            Required critical value = 21.026

b] alpha =0.01, r=7, c=4           df = (r-1)(c-1) = 18            Required critical value = 34.805

c] alpha =0.01, r=7, c=3           df = (r-1)(c-1) = 12            Required critical value = 26.217

d] alpha =0.01, r=4, c=3           df = (r-1)(c-1) = 06            Required critical value = 16.812

e] alpha =0.01, r=3, c=5           df = (r-1)(c-1) = 08            Required critical value = 20.090
