According to a report published by the Pew Research Center in February 2010, 61% ofMillennials (Americans in their teens and 20s) think that their generation has a uniqueand distinctive identity (N= 527).8a. Calculate the 95% confidence interval to estimate the percentage of Millennialswho believe that their generation has a distinctive identity as compared with theother generations (Generation X, baby boomers, or the Silent Generation).b. Calculate the 99% confidence interval. c. Are both these results compatible with the conclusion that the majority ofMillennials believe that they have a unique identity that separates them from theprevious generations?

Suppose you find that the 95% confidence interval for the cost of a wedding is ($29,000, $35,000). What is the correct interpretation of this interval? Group of answer choices For the next wedding you attend, the cost will be between $29,000 and $35,000. There is a 95% probability that the sample mean is between $29,000 and $35,000.
