Questioningbon An American company that manufactures computers from different brands (Apple Hp Lenovo) wants to determine whether there are anyone in the quality of work among the three PC brands. They randomly selected 496 PCs and carefully inspect them Each PC is either assified as perfect, actory or defective and the brand that produced it is also recorded. The two categorical variables of interest we the PC brand and condition of the PC produced. The data can be su by the accompanying two-way table Does the data provide suficient evidence at the significance level to inter that there are differences in quality among the three rande?
