LEARNING COMPETENCY: The learners draw a conclusion about the population mean based on the test-statistic value and the rejection region. PERFORMANCE STANDARD: The learner is able to perform appropriate tests of hypotheses involving the population mean μ and population proportion to make inferences in real-life problems in different disciplines. SITUATION: You are working in a company facing attrition problems of the customer service representatives for the past five years. The company president proposed that if the attrition rate is at least 10 per month, then the salary scale, compensation package, and professional development programs for employees will be initiated.
