You are a researcher wanting to examine support for the Mayor of your hometown. You complete a survey (using a probability sample) of 1000 residents registered to vote and find that 68% of your sample approves of the job the Mayor is doing (standard error = 1.5). We now want to calculate how close our findings are to the mayor's actual approval rating among your hometown's residents. Please use this information to answer questions #9-10.

A study considered the question, 'Are you a registered voter?" Accuracy of response was confirmed by a check of city voting records. Two methods of survey were used: a face-to-face interview and a telephone interview. A random sample of 85 people were asked the voter registration question face to face. Of those sampled, seventy-six respondents gave accurate answers (as verified by city records). Another random sample of 90 people were asked the same question during a telephone interview. Of those...
