Construct a confidence interval of the population proportion at the given level of confidence. x = 125, n = 250, 90 % confidence.
the 90% confidence interval is
(use ascending order. round to three decimal places as needed.)

90% confidence interval would be (0.448, 0.552).

Step-by-step explanation:

Since we have given that

x = 125

n = 250

So,

We need to find the 90% confidence interval.

so, z = 1.64

So, interval would be

Hence, 90% confidence interval would be (0.448, 0.552)
