The answer to your question is 915.75 I think
The given values are:
p = 22% = 0.22
Zc = 1.645 at 90% confidence level.
margin of error, E = 0.04
The formula we can use here is:
E = sqrt(pq/n) * Zc
0.04 = sqrt(0.22*(1-0.22)/n)*1.645
n = (0.22*(1-0.22))*(1.645/0.04)^2
n = 290.22
hence minimum sample size = 290
Answer:
3/4 = z
Step-by-step explanation:
<u>Step 1: Convert words into an expression</u>
Divide 3 by 4, then subtract z from the result
3/4 - z
<u>Step 2: Solve for z</u>
3/4 - z + z = 0 + z
3/4 = z
Answer: 3/4 = z
