<PRE><B>Question 831419</B>
We controlled 30 products and 2 of them were broken. Compute the confidence interval with 95% reliability for probability p, that the product is broken.
------
p-hat:: 2/30 = 1/15 = 
ME = 1.96*sqrt[(1/15)(14/15)/30] = 0.0893
-----
95% CI: 0.0667-0.0893 &lt; p &lt; 0.0667+0.0893
