Answer:
The required critical values is ±1.65
Step-by-step explanation:
Consider the provided information.
We have given that the significance level is 0.10
Therefore, α=0.10
This is a two tailed test.
The Z critical value is: [tex]Z_{\frac{\alpha}{2}}[/tex]
[tex]Z_{\frac{\alpha}{2}}=Z_{\frac{0.10}{2}}=0.05[/tex]
Now by using the table we can find the required value.
[tex]Z_{\frac{\alpha}{2}}=1.645[/tex]
[tex]-Z_{\frac{\alpha}{2}}=-1.645[/tex]
Hence, the required critical values is ±1.65
