Next we need to determine the critical value if we want to perform the test
using the classical approach. Since we were asked to perform the test at the
5% level of significance and there are 5 categories, then we need to
determine
. Observe that
= 5 and the degrees of freedom
=
– 1
= 5 – 1 = 4. We can use the
