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

The  value is  

Step-by-step explanation:

From the question we are told that

     The null hypothesis is  

     The level of significance is  

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

Hence the critical value is  

f is the midpoint of
