Answer:
2.6 meters.
Step-by-step explanation:
5-0.9 is 4.1, minus 1.5 is 2.1.
Answer:15
Step-by-step explanation:
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
