Respuesta :
The critical value of Z at the level of confidence c=0.94 is z = 1.91.
According to the statement
we have given that the a confidence interval at the level of confidence c=0.94. And we have to find the critical value of the z.
So, For this purpose, we know that the
Critical value can be defined as a value that is compared to a test statistic in hypothesis testing to determine whether the null hypothesis is to be rejected or not.
So, The given confidence interval is 0.94
Then
1- 0.94 = 0.6.
So, critical value for the 0.6 according to the table is
z = NORM SINV(.06/2)= 1.9112
And we know that the
The value of z with given confidence interval is
90%
z =1.645
92%
z = 1.751
95%
z = 1.96
98%
z = 2.326
So, The critical value of Z at the level of confidence c=0.94 is z = 1.91.
