Anather finding was that 429% of these agedt 18 to 24 use Twitter. Assume the sample se assoated with both findings is 400. (a) Develop a 95% confidence interval for the proportion of adults aged 18 to 24 who use Snapchat. (Round your answers to four decimal piaces. to (b) Develop a 09 conhdence nterval fe the aneportion of adute aged 24 who use Twitter (Rund your aneners to four decmal paes) () In which case, part (a) or part (b). the margin of error larger Explain why The margin of error i larger in aged 18 to 24 who use inapchat. Therefore, the standard error of the former is elect than the sample propertion of aduts the latter In addition, for a 99% confidence interval i for bwo reasons, The sample proportion af adults aged 18 24 who use Twitter than the standant emer for a 95 confidence interval.
