Step 1
Express the expression for the confidence interval.
C.I=p±Zp(1p)n
Here, Z* is the critical value .
From the Z table, the value corresponding to the region 90.5 is,
Z=1.31
Step 2
Put 590 for n, 0.93 for p, 1.31 for Z* implies,
C.I=0.93±1.310.93(10.93)0.93
C.I=0.93±0.346
Thus, the confidence interval is 0.93+0.346 and 0.930.346.
