Answer
# Brief Explanations:
A sample proportion estimates the population proportion. Since it's a random sample, it gives a likely estimate but not an exact value. Different random samples may have different proportions. The sample proportion of 30% suggests it is likely that about 30% of the students at the school use the app.
# Answer:
A. It is likely that about 30% of the students at her school use the app.
