The company 's annual report states, "Our survey shows that 87.34% of our employees are 'very happy 'working here." Comment on that claim. Use appropriate statistics terminology.

Solution

VerifiedThe people who respond to a survey is only a part of the entire population of all employees of the company.

The proportion of respondents are "very happy" is then a sample statistics (descriptive measure of a sample), while the proportion of all workers that are "very happy" is a population parameter (descriptive measure of a population).

Since a sample statistic estimates a population parameter, they might be close in value but they are most likely not equal.

The claim is thus not completely correct, a better claim would be: "87.34% of the surveyed employees were "very happy" working here".
