商品敘述：
An investor, Janice Zhuk, examines Tesla''s quarterly safety data that includes the number of miles it took to register one accident among Tesla cars driving with autopilot versus those without autopilot. The data set is small, so the validity of any statistical analysis may be compromised. The data allow one to run a simple t-test comparison of means. Because of the small sample size, the case invites a discussion on the hypothesis of the regression model, in particular, the normality of the residuals.
