The number is 12
16 plus 8 = 24/ 2= 12
Given:
p = 20% = 0.2, sample proportion
n = 5000, sample size.
Confidence level = 95%
The confidence interval is
(p - 1.96k, p + 1.96k)
where

Therefore the 95% confidence interval is
(0.1943, 0.2057) = (19.4%, 20.6%)
Answer: The 95% confidence interval is (19.4%, 20.6%)
Answer:

Step-by-step explanation:
Using the slope formula:

8<-5x+20 is one possible answer. it depends on how they are writing it. you need to do the distributed property.
