To estimate how many students in the entire school have a younger sibling, we can first find the proportion of students in Nate's sample who have a younger sibling.
In Nate's survey:
- Total students surveyed = 25
- Students with a younger sibling = 14
The proportion of students with a younger sibling in the sample is:
\[ \text{Proportion} = \frac{14}{25} \]
Now we'll use this proportion to estimate how many students in the entire school (800 students) are expected to have a younger sibling. We will multiply the proportion by the total number of students in the school.
First, calculate the proportion:
\[ \text{Proportion} = \frac{14}{25} = 0.56 \]
Now we multiply this proportion by the total number of students in the school:
\[ \text{Expected number of students with a younger sibling} = 0.56 \times 800 \]
Calculating that:
\[ 0.56 \times 800 = 448 \]
Thus, we would expect 448 students in the entire school to have a younger sibling.
