Answer:
The value is [tex]z = \pm 1.645[/tex]
Step-by-step explanation:
From the question we are told that
The number of observation is greater than 50 i.e. n > 50
The level of significance is [tex]\alpha = 0.1[/tex]
Generally given that n > 30 then we will make use of the z table
So
From the z table the critical value corresponding to the level of significance level for a two-tailed test is
[tex]z = \pm 1.645[/tex]
