perform the hypothesis on the following scenarios. 1. The minimum wage earners of the National Capital Region are believed to be receiving less than Php5,000 per day. The CEO of large supermarket chain in the region is claiming to be paying its contractual higher than the minimum daily wage rate of Php500.00. To check on his claim, a labour union leader obtained a random sample of 144 contractual employees from this supermarket chain. The survey of their daily wage earning resulted to an average wage of Php510.00 per day with standard deviation of Php100.00. 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.
