For this case we have the following factorized expression:
Applying distributive property we have:
We add similar terms taking into account that: Equal signs are added and the same sign is placed.

Answer: z= -2.35
Step-by-step explanation:
When the population variation is know, then we calculate the z-statistic.
Formula to calculate the z-test statistic is given by :-
where , n= sample size
= sample mean
= Population mean
=Population standard deviation.
As per given we have,
n= 270
Then, z-statistic will be
(Substitute all the values )
Hence, the value of the test statistic= z= -2.35
