Question

Express the confidence interval 0.333< p < 0.999 in the form p±E.

Answer 1

Answer:

Therefore, the final form

p+/-E = 0.666+/-0.333

Step-by-step explanation:

Given:

Confidence interval = 0.333 < p < 0.999

To express the confidence interval in the forn p+/-E, where;

p is the midpoint of the confidence interval

E is the error.

The midpoint of the confidence interval is

p = (0.333+0.999)/2 = 1.332/2

p = 0.666

The error can be calculated using the formula:

Error = interval width/2

E = (0.999-0.333)/2 = 0.666/2

E = 0.333

Therefore, the final form

p+/-E = 0.666+/-0.333
