The correct answer is:
1.03
Explanation:
We will use a z-table to do this.
84.85% = 84.85/100 = 0.8485; this is the value we look for in the middle of the table. Once we find it, we see the number to the left is 1.00; above it we have 0.03. This means that 1.00+0.03 = 1.03 is the z-score for this value.
