This was a legitimate sample, drawn randomly from his readers, and is of adequate size to allow the conclusion that most of Remy's readers want to be famous.

100%- 42% = 58%,
Actual No readers = 42% of 2200 = 924 readers,
Actual Yes readers = 58% of 2200 = 1276 readers

which agrees with the option E
This was a legitimate sample, drawn randomly from his readers, and is of adequate size to allow the conclusion that most of Remy's readers want to be famous.
