Answer:

The  value is  1.75 \  and  \   -1.75

Step-by-step explanation:

From the question we are told that

     The null hypothesis is  H_1 :  \mu \ne 3.24

     The level of significance is  \alpha = 0.08

From the z table  the critical value of  \alpha considering the two tails of the normal  curve( This is because this a two tailed test ) is

       z= \pm  1.75

Hence the critical value is  

       1.75 \  and  \   -1.75
