The categories of a categorical variable are given along with the observed counts from a sample. The expected counts from a null hypothesis are given in parentheses. Compute the -test statistic, and use the -distribution to find the p-value of the test.

Category A B C D
Observed (expected) 60 (60) 111 (120) 166 (180) 254 (240)

What is the chi-square statistic and what is the p-value?
