Question 5 (15 marks): Prior to the pandemic, an organization surveyed 1100 adults to see whether they have been out of the country for a vacation. Of the 1100 adults surveyed, 407 indicated that they have vacationed out of the country. In a survey post-pandemic, the same question was asked of 1100 adults and 333 indicated that they have been on a vacation outside the country. Has the proportion of adults who have had a vacation outside the country changed? Use the \alpha =0.05 level of significance. Ensure to explain what the conclusion means in terms of the question's context (i.e., not just reject or fail to reject). Use both the classical approach and P -value methods and write down all formulas used. Also, construct a 95% confidence interval.
