Question

Express the confidence interva l0.555< p < 0.99 in the form p+-E.

Answer 1

The confidence interval in the form p+E is p ± E = 0.7725 ±0.435

How to rewrite the confidence interval?

The confidence interval is given as:

0.555< p < 0.99

To rewrite the above expression in the form p+E, we use the following equations

p = (0.99 + 0.555)/2 = 0.7725

E = (0.99 - 0.555) = 0.435

So, we have:

p ± E = 0.7725 ±0.435

Hence, the confidence interval in the form p+E is p ± E = 0.7725 ±0.435
