Assume Null Hypothesis as Ho: Independence of categorical variables (customer order forms defective % does not varies by centre) Thus, Alternative hypothesis as Ha Dependence of categorical variables (customer order forms defective % varies by centre)
Inference: As (p_value = 0.2771) > (α = 0.05); Accept Null Hypthesis i.e. Independence of categorical variables Thus, customer order forms defective % does not varies by centre.
