Step-by-step explanation:

The upper confidence limit for the 90% confidence interval would be 0.415.

Step-by-step explanation:

Since we have given that

n = 400

x = 150

So,

At 90% confidence interval, z = 1.645

So, margin of error would be

So, the upper limit would be

Hence, the upper confidence limit for the 90% confidence interval would be 0.415.
