A study by Consumer Reports showed that 72% of pet owners believed supermarket pet food brands were as good as or better than organic name brands in terms of product quality. To investigate whether this result applies to its own product, the manufacturer of a supermarket brand of pet food product asked 100 pet owners whether they believed their company's supermarket brand of pet food was as good as or better than the organic name-brand pet food. Data from the pet owner sample found that 74 of the owners indicated that the supermarket brand was as good as or better than the organic name brand. Show work if necessary.
