Answer:
1770
Step-by-step explanation:
We need to estimate number of households to be sampled to construct a 99% confidence interval.
Number of households to be sampled=n=?


The proportion can be estimated as
p=x/n.
We know that 24 out of 40 households owns their home.
so, x=24 and n=40.
p=24/40
p=0.6
q=1-p=1-0.6=0.4
pq=0.6*0.4=0.24
E=0.03



n=1769.56.
n=1770.
Thus, the number of households that need to be sampled are 1770.
The amount of medicine in the bloodstream decreases by 25% each hour.
<h3>Exponential equation</h3>
The standard exponential equation is expressed as:
y = ab^x
a is the initial amount
b is the rate
If b < 1, hence there is a declince
Given the expoenentia equation A(h)=600(0.75)^h,
b = 1 - r = 0.75
r = 1 - 0.75
r = 0.25
This shows that the amount of medicine in the bloodstream decreases by 25% each hour.
