Extracted text: For items 9 to 13, refer to the given situation: Hauz of Gaz claims that more than two-thirds of the houses in a certain subdivision use their brand. Is there a reason to doubt this claim if 25 out of a random sample of 40 houses in the subdivision | use the company's brand? Test the claim at 0.01 level of significance. 9. What are the null and alternate hypotheses? A. Ha:p = 0.67; H9:p # 0.67 B. Hạ:p + 0.67; Ho:p = 0.67 C. Haip > 0.67; H9:p # 0.67 D. Ha:p > 0.67; Họ:p = 0.67 10.
