Recap: Statistical Inference with infer

Sampling scenarios

We performed both tactile and virtual sampling exercises to infer about an unknown proportion. We also presented a case study of sampling in real life with polls. In each case, we used the sample proportion $\hat{p}$ to estimate the population proportion $p$. However, we aren’t just limited to scenarios related to proportions. In other words, we can use sampling to estimate other population parameters using other point estimates as well. We present four more such scenarios in the table below.
