Question

PLEASE ANSWER!!!

Russell surveys 200 randomly selected seventh-graders in his school and finds that 30 attend summer camp. If there are 780 seventh-graders in his school,
about how many are expected to attend summer camp?

Answer 1

117 seventh-graders in the school are expected to attend summer camp.

Explanation:

Answer 2

To estimate the number of seventh-graders who attend summer camp, we can use the sample proportion of 30 out of 200 students.

Let's call the population proportion of seventh-graders who attend summer camp "p".

The sample proportion can be estimated as:

p = 30/200 = 0.15

To estimate the number of seventh-graders in the entire school who attend summer camp, we can multiply the population size by the sample proportion:

Estimated number of seventh-graders attending summer camp = p * population size = 0.15 * 780 = 117

So, about 117 seventh-graders in the school are expected to attend summer camp.
