The critical value that corresponds to a 94% confidence level is 1.88
The confidence level is given as:
CL = 94%
Express as percentage
CL = 0.94
Calculate the significance level
α = 1 -0.94
α = 0.06
Divide by 2
α/2 = 0.06/2
α/2 = 0.03
Subtract from 1
1-α/2 = 1-0.03
1-α/2 = 0.97
The above represents the proportion (p).
So, we have:
p = 0.97
Using the z table,
The critical value at a proportion of 0.97 is approximately 1.88
Hence, the critical value that corresponds to a 94% confidence level is 1.88
