Step-by-step explanation:

Given that a researcher collected data on Americans leisure activities.  Mean number of hours spent watching TV X is having mean 2.7 and std deviation 0.2.

Null hypothesis should be mu =2.7

and alternate hypothesis should be mu <2.7

We compare sample mean with population mean.
