Find the critical value zc that corresponds to a 94% confidence level
4 months ago
Q:
Find the critical value zc that corresponds to a 94% confidence level
Accepted Solution
A:
Zc at 94% confidence level
Step 1: α = 100 -94 = 6% = 0.06
Step 2: α/2 = 0.06/2 = 0.003
Step 3: 1-α/2 = 1-0.003 = 0.97
From Z-tables and at proportion of 0.97 (area under curve),
Zc ≈ 1.88
