General Directions: As a competent Columbanite, do the following activities for written works and performance tasks. Perform the test of hypothesis on the following scenarios. 1. The minimum wage earners of the National Capital Region are believed to be receiving less than Php 5,000.00 per day. The CEO of a large supermarket chain in the region is claiming to be paying its contractual higher than the minimum daily wage rate of Php 500.00 To check on this claim, a labour union leader obtained a random sample of 144 contractual employees from this supermarket chain. The survey of their daily wage earnings resulted to an average wage of Php 510.00 per day with standard deviation of Php 1o0.00. The daily wage of the region is assumed to follow a distribution with unknown population variance. Perform a test of hypothesis at 5% level of significance to help the labour union leader make an empirical based conclusion on the CEO's claim.
