A small cleaning service company obtains a contract proposal from a customer owning an office tower with 100 rooms. The company has only 5 workers. It needs to determine its profit margin by first finding out the time required by the workers to finish cleaning 100 rooms. The first estimation is that the workers would need 5.5 hours to clean the 100 rooms. The company starts a probation period for two week, while collecting data so that it can later charge the customer correctly. The data collected by the company can be seen on the next table. After collecting this data, the company wants to determine if the first estimation of 5.5 hours to finish cleaning 100 rooms was reasonable. If the computed t-value falls between -to.025 and to.025, the company would be satisfied and will stay with its first estimation. What is your opinion?
