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. For this purpose, attrition rates for 20 months selected at random were considered and listed below.

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. For this purpose,
attrition rates for 20 months selected at random were considered and listed below. Assume
that the data follow normality.
