Question 7: For any confidence level C, the value of the sample proportion will always be considered a plausible value for p. (а) True (b) False Question 8: The Normal approximation to the sampling distribution for a population proportion will be adequate for a study with a sample size of 25 and a proportion of 0.9. (а) True (b) False Question 9: The following statements are attempts to interpret the 95% confidence interval (0.157, 0.179) for the proportion of Canadian adults that own a cat. Select all of the statements that are correct interpretations. (a) 16.8% of Canadian adults own a cat. (b) The most likely proportion of Canadian adults that own a cat is 16.8% (c) We don't know the true proportion of Canadian adults that own a cat, but we know it's within the interval (0.157, 0.179). (d) There is a 95% chance that the true proportion of Canadian adults that own a cat is within the interval (0.157, 0.179). (e) With repeated sampling, a confidence interval of this level will contain the true proportion of Canadian adults that own a cat 95% of the time.
