Extracted text: A market research firm conducts telephone surveys and the historical population proportion response rate (Hint: the population proportion (parameter) is KNOWN for this problem) for surveys is known to be 0.43 (i.e., the population response rate parameter p = 0.43 is known). Assume the firm surveys a total of 500 customers during a project. What is the probability that 225 customers or LESS (out of 500 surveyed) will respond to the survey? About 22.5% 0.5 0.747 0.817
