On a particular day, the results of a question were tallied. In all, 636 said "Yes, " another 595 said "No, " and the remaining 93 indicated that they were not sure. What is the sample size for this poll? Compute the percent of responses in each of the possible response categories. (Round your answers to two decimal places.) Discuss the poll in terms of the population and sample framework that we have studied in this chapter. This random sample of responses collects the opinions of a random group of users across all users of the Internet. This voluntary response sample collects only the opinions of those that visit this site every day. This random sample of responses collects the opinions of a random group of users of the particular site. This voluntary response sample collects only the opinions of those who visit this site and feel strongly enough to respond.Explanation / Answer
Answer:
From the data given, number of respondent who said "Yes" =636
number of respondent who said "No" =595
number of respondent who were Not Sure =93
1. Therefore total number of respondents = Sample size = 636+595+95 = 1324 responses
2. Percent of response in each category:
Yes = (636*100)/1324 = 48.03%
No = (595*100)/1324 = 44.94%
Not Sure = (93*100)/1324 = 7.02%
c) This voluntary response sample collects only the opinions of those who visit this site and feel strongly enough to respond.
