The formula for the confidence interval for sample proportion is:

where,

are the sample proportion in which we are interested.

So,

and

we have to find for 99% confidence interval, we need to look up at the Z- table.

i.e.

Now, the margin of error =

Thus, the confidence interval obtained as:

at 99% confidence level.

=====================================================================================

1-24/(1.) <P < Þ+z/p(1. – )

p = 47 100 = 0.47

47 1 - p = 1- * 100 = 1 -0.47 = 0.53

Z2 = 20.99 = 20.495 = 2.58

2.58 * / 0.47 +0.53 " = 2.58 +0.0499 = 0.1287 100

0.47 -0.1287 < P < 0.47 +0.1287 0.3413 < P < 0.5987
