Happyville Exercise Your job: Estimate the mean number of residents per household in the town of Happyville. There are 100 households, as shown on the accompanying illustration (adapted from Aliaga & Gunderson's, Interactive Statistics). Since we don't have the time or resources to go to every one of these households, we will take a small sample of them and use the results to estimate the mean for the entire town. We will be trying out different methods for obtaining our...
