At a significance level of .05,the management wants to perform a hypothesis test to determine if the quality of the items produced appears to be independent of the production process used.Based on the results summarized in the MegaStat/Excel output provided in the table above,we:

• A)Reject H₀ and conclude that the quality of the product is not the same for all processes.
• B)Reject H₀ and conclude that the quality of the product is dependent on the manufacturing process.
• C)Do not reject H₀,and conclude that the quality of the product does not significantly differ among the three processes.
• D)Do not reject H₀,and conclude that the quality of the product is not the same for all processes.
• E)Reject H₀ and conclude that the quality of the product is independent of the manufacturing process used.
