Many people believe that they experience "information overload' in today's digital world. A report describes a survey in which people were asked if they feel overloaded by information. Suppose in a representative sample of 634 college graduates, 102 indicated that they suffered from information overload, while 118 people in an independent representative sample of 496 people who had never attended college said that they suffered from information overload.
(a) Construct a 95% large-sample confidence interval for the proportion of college graduates who experience information overload. (Hint: This is a one-sample confidence interval. Use a table or technology. Round your answers to four decimal places.)
(b) Construct a 95% large-sample confidence interval for the proportion of people who have never attended college who experience information overload. (Use a table or technology. Round your answers to four decimal places.)
(c) Construct a 95% large-sample confidence interval for the difference in the proportions who have experienced information overload for college graduates and for people who have never attended college. (Use p1 − p2 where p1 is the true proportion of college graduates who experience information overload and p2 is the true proportion of those who have never attended college who experience information overload. Use a table or technology. Round your answers to four decimal places.)
