Question

A watchdog agency reported indicated that, due to COVID-19, more than 70% of employees in high-tech areas have shifted from office work to work from home. An advisory group decided to investigate this claim, believing it was too large. A random sample of 400 employees from a few states showed that 300 work from home. Using the 0.02 significance level, can we conclude that more than 70% of employees in high-tech areas work from home?
