15. Sampling consumer data may be your only option due to time and cost constraints. Yet that will lead to sampling error, thus we do confidence intervals to lay out our certainty levels of our data findings. Please calculate a confidence interval for the percent of your customers you expect to go unsatisfied. You surveyed 76 customers and found that 22% of them were unsatisfied. You wish to be 97% confident when stating this interval range. The population of customer data is 600 surveys. Round your answers to the thousandth place. Hint: FPCF?
