Course: AP®︎/College Statistics > Unit 6. Lesson 3: Random sampling and data collection. Techniques for generating a simple random sample. Simple random samples. Techniques for random sampling and avoiding bias. Systematic random sampling. Sampling methods. Sampling method considerations.To find mean, we add up the values in a set and divide by the number of terms in that set. We begin this problem with the knowledge that the mean of the first set is 20. Since that set contains five numbers, we know that its total sum must be 100 (since 100 divided by 5 is 20). so must be 25. Now, the only step left is to find the mean of .

7.SP.A.2 — Use data from a random sample to draw inferences about a population with an unknown characteristic of interest. Generate multiple samples (or simulated samples) of the same size to gauge the variation in estimates or predictions. For example, estimate the mean word length in a book by randomly sampling words from the book; predict the …
