Given that The mean length of time in jail from the survey was four years with a standard deviation of 1.9 years.
The above given is for sample of 27 size.
For hypothesis test to compare mean of sample with population we can use either population std dev or sample std dev.

So here we can use population std deviation 1.4 only.
If population std deviation is used we can use normality and do Z test
