Question

TTYL The online security firm SecurEnvoy and the research firm OnePoll conducted a telephone survey in October 2012 and found that 60% of Britons admit they don't always understand text message abbreviations they receive. The firms surveyed 1000 British adults. (http:// tsminteractive.com/have-you-ever-been-confused-by -text-message-abbreviations-poll/) 
Assuming that this was a simple random sampling, can you be comfortable that 60% is a good estimate of the percentage of British adults who don't always under- stand text messages. 
A) Yes. A simple random sample always gives more accurate results than other methods of sampling. 
B) Yes. As long as the question asked was free of bias, you can trust the results. 
C) No. Telephone surveys are never accurate. 
D) No. Younger adults probably understand more text abbreviations than older adults. We would be more confident in the results of a sample that was stratified according to age.
