Answer:
The value is [tex]1.75 \ and \ -1.75[/tex]
Step-by-step explanation:
From the question we are told that
The null hypothesis is [tex]H_1 : \mu \ne 3.24[/tex]
The level of significance is [tex]\alpha = 0.08[/tex]
From the z table the critical value of [tex]\alpha[/tex] considering the two tails of the normal curve( This is because this a two tailed test ) is
[tex]z= \pm 1.75[/tex]
Hence the critical value is
[tex]1.75 \ and \ -1.75[/tex]
