Solve the problem.A political poll has a built in error tolerance. A candidate receiving 35% support, according to the poll, could actually have 37% support and the poll would still be considered accurate. The error tolerance for the candidate with 35% support is 3%. An acceptable percentage p for the candidate must satisfy the inequality
? 3. Solve the inequality and interpret the result.
A. {p}; Actual support for the candidate could vary between 35% and 38%.
B. {p};Actual support for the candidate could vary between -3% and 3%.
C. {p}; Actual support for the candidate could vary between
and 38%.
D. {p}; Actual support for the candidate will not vary because you cannot have negative percentages.
