Question

Dana plans to use a survey of 60 randomly selected students at her school to predict the percentage of the 900 students at her school who will attend next week's school dance. How can Dana change her data collection plans to make her prediction closer to the actual result?​

Answer 1

See below ~

Explanation:

Dana takes a survey of 60 students out of 900 total to see how many will attend the dance.

Based on whatever result she gets out of the 60 students, she can take that number and multiply it by 15 to get a closer prediction to the actual result.

• This is because 60 x 15 = 900
• We are basic taking a ratio of the smaller portion so we can estimate the value of the larger group
