Question

Assume that the data has a normal distribution and the number of observations is greater than fifty. Find the critical z value used to test a null hypothesis.
α = 0.08; H1 is μ ≠ 3.24

Answer 1

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  

       $1.75 \ and \ -1.75$
