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
