## 3.6 Activity: Introduction to estimation: Monday Breakups

In a previous course activity, we found that breakups are more likely to happen on Mondays. But just how likely are Monday breakups? In this activity, you will address the following question,

What proportion of breakups are reported on Mondays?

The evidence we have comes from a sample. In a random sample of 50 breakups on Facebook, 26% were reported on Monday. The research question, though, is about all breakups reported on Facebook, not just the breakups in the sample. Thus, we are interested in estimating a population parameter (the proportion of all breakups reported to Facebook) based on a sample.

Sample: Random sample of 50 breakups reported to facebook.

Population: All breakups reported to facebook

In this activity we’ll explore how statisticians go about estimating a population parameter using data from a sample.
