It provided a variety of statistics on internet users. (a) (b) (C) (d) The sample survey showed that 94% of respondents said the internet has been a good thing for them personally. Develop a 95% confidence interval for the proportion of respondents who say the internet has been a good thing for them personally. (Round your answers to four decimal places.) to The sample survey showed that 68% of internet users said the internet has generally strengthened their relationship with family and friends. Develop a 95% condence interval for the proportion of respondents who say the internet has strengthened their relationship with family and friends. (Round your answers to four decimal places.) to Fifty-four percent of internet users have seen an online group come together to help a person or community solve a problem, whereas only 25% have left an online group because of unpleasant interaction. Develop a 95% confidence interval for the proportion of internet users who say online groups have helped solve a problem. (Round your answers to four decimal places.) Compare the margin of error for the interval estimates in parts (a), (b), and (c). How is the margin of error related to the sample proportion E? The margin of error decreases as 5 gets closer to 0.50. " The margin of error does not change as 5 gets closer to 0.50. The margin of error increases as ,3 gets closer to 0.50
