Question

random sampling
area is a large forest. you want to count the population of a species of mouse in
you divide the forest into a grid of 25 plots (squares)
id, you randomly select 5 plots to survey.
nice in each sample plot:
grid to see the number of mice counted in 5 sample plots.
find the total population size by random sampling:
total mice in 5 squares: ______________ (add 5 numbers)
average number of mice in each square: ______________
estimate of total population:
(average x number of squares)

Explanation:

Step1: Sumar los 5 números

$17 + 8+12 + 11+16$

$$\begin{align*} &17+8 = 25\\ &25+12=37\\ &37 + 11=48\\ &48+16 = 64 \end{align*}$$

Step2: Calcular el promedio

Promedio $=\frac{\text{Total}}{5}=\frac{64}{5}=12.8$

Step3: Estimar la población total

Número de cuadrados $=25$
Población total estimada $=12.8\times25$
$$12.8\times25=(12 + 0.8)\times25=12\times25+0.8\times25=300 + 20=320$$

Answer:

Total mice in 5 squares: $64$
Average number of mice in each square: $12.8$
Estimate of total population: $320$
