Estimate of population 0.61
(b) Margin of error = 0.07 The real population interval estimation is ± 7%.
c). Margin of error = 0.15
d) The real population's interval estimation is ± 15%
e). Yes, the action argument of the group is based on a half-range estimation of the true population. The reason that 62% ± 15% = 47%, or 77%, while 47% is similar to 45%, as the Collective action group states. Hope this helps! Mark Brainly please!
Answer:
Step-by-step explanation:
<u>We can describe it as a linear function with points of:</u>
<u>Slope intercept formula:</u>
<u>Finding the slope using the two given points:</u>
- m = (4600-2000)/(15-5) = 2600/10 = 260
<u>Finding b:</u>
<u>Formula obtained:</u>
<u>For x = 20, value of y is:</u>
- y = 260*20 + 700 = 5200+700 = $5900

This is the concept of exponential growth;
the formula for obtaining the number of bacteria at time t in future is:
f(t)=ae^(kt)
where;
f(t)=population in future
a=initial population
k=constant of proportionality.
suppose the initial population was x, when the population doubles it will be 2x at a future time t.
k=0.027
thus substituting the above in our formula we get:
2x=xe^(0.027t)
solving for t we get:
2=e^(0.027t)
introducing the log function we get:
ln2=0.027t
thus;
t=(ln2)/0.027
=25.67
therefore;
t=25.67 hours
