ModernDive 0.6.0

We're only a few cosmetic edits away from v1.0.0, which will correspond to our print edition with CRC Press!

Done first pass of infer chapters

Completed major re-organization and clean-up of Chapters 9-11 using the infer package for "tidy and transparent" statistcal inference.

Chapter 9: Bootstrapping & confidence intervals
- Tactile exercise of sampling 50 pennies from bank and resampling from this sample.
- Added sections on
  1. "Interpreting confidence intervals", in particular determinants of CI width.
  2. "Theory-based confidence intervals" using formula for SE of p-hat, thereby bridging gap between simulation and theory-based methods.
Chapter 10: Hypothesis testing
- Added promotions example on gender discrimination in promotions at a bank. Data source: openintro::gender.discrimination
- Added section on "Theory-based hypothesis tests" using t-test, thereby bridging gap between simulation and theory-based methods.
Chapter 11: Inference for regression.
- Discussion on LINE conditions for inference. In particular using moderndive::get_regression_points() wrapper function to broom::augment() so that novices can do their own residual analyses.

Chapter 7: Multiple regression
- Added Section 7.3.1 on model selection: choosing between "interaction" and "parallel slopes" models
Chapter 8: Sampling
- Added Section 8.5.3 with more in-depth discussion of normal distribution
Chapter 12: Renamed to "Tell your story with data"
