Well in words, H0 is that the mean for the new licence training is the same as the mean for the old training. And H1 is the that H0 is not true, i.e. they are different. It's a little hard to be certain how they want you to enter this with the symbols they give you but perhaps something like:

H0 is µ = x̄ and

H1 is µ =/= x̄

or

µ1 = µ2 

µ1 =/= µ2


But there's no way to know for certain what they want, since the question doesn't define the symbols for each scenario. So I'm using µ1 to mean the population mean of the time to receive a new licence, and µ2 to be the population mean of the time taken following the new training.

It's also possible you should replace µ1 with 11.5, e.g. write something like:

µ = 11.5

µ =/= 11.5
