X1 - 3 = x2
subtract 3 from the first value to get the second one
Answer:
5901
Step-by-step explanation:
The margin of error is the critical value times the standard error.
ME = CV × SE
For α = 0.05, the critical value is z = 1.96.
The standard error of a proportion is √(pq/n). Given p = 0.04, then q = 1−p = 0.96.
The margin of error is 0.5% or 0.005.
Plugging in:
0.005 = 1.96 √(0.04 × 0.96 / n)
n ≈ 5901
Answer:
They average 84%
Step-by-step explanation:
Just add 77 and 91 then divide it by 2. Hope this helps.
Multiple so it’s 20 Bc 5x4=20 or you would add do the math you will figure it out
