Question

8. The following table shows how high school students in four grade levels ate

Answer 1

Answer:

D .27

Step-by-step explanation:

As you can observe in the table, 45 Junior students purchased lunch off-campus. The total Junior surveyed were 50+70+45 = 165. So, 45 out of 165 purchased lunch off-campus.

To find the proportion of Juniors who purchased lunch off-campus, we just need to divide

$p=\frac{45}{65} \approx 0.27$

Therefore, the right answer is D.
