Final answer:
The original claim that 'at most 48% of Internet users pay bills online' can be expressed symbolically as 'p ≤ 0.48,' where 'p' represents the percentage of Internet users who pay their bills online.
Step-by-step explanation:
The original claim that at most 48% of Internet users pay bills online can be expressed in symbolic form using inequalities. The symbol ≤ (less than or equal to) is used to represent 'at most.' Therefore, if 'p' represents the percentage of Internet users who pay their bills online, the claim can be written as:
p ≤ 0.48
This means that the percentage of Internet users who pay bills online is 48% or less. In the context of the recent survey mentioned, where 45% of the 388 surveyed Internet users pay their bills online, if we were to express this as a symbolic inequality, it would be p = 0.45, which is consistent with the initial claim.
