In 2007, a Gallup poll estimated that 45% of U. S. adults rated their financial situation as "good." We want to know if the proportion is smaller this year. We gather a random sample of 100 U. S. adults this year and find that 39 rate their financial situation as "good." After carrying out a hypothesis test for p = 0.45, we obtain a p-value of 0.114. Determine whether each of the following statements about the p-value is valid or invalid. A. There is an 11.4% chance that the percentage of adults who rate their financial situation as "good" is still 45%. B. There is an 11.4% chance that the percentage of adults who rate their financial situation as "good" is now less than 45%. C. If the percentage of adults who rate their financial situation as "good" is still 45%, there is an 11.4% chance that a random sample of size 100 would have a sample percentage of 39% or lower.
