8. Is validation, such as k-fold cross- validation, able to determine that the model structure is poorly chosen? Yes No 9. As part of a gender bias study, your university examines the average grade obtained by women in STEM classes against the average grade obtained by men. In the preceding question, further analysis shows that the fraction of women is approximately the same across all STEM classes considered, and the enrolment numbers are also approximately the same. However, the extent of difference in grades between women and men varies widely across classes. Given the above information, can we be sure that Simpson's paradox will not happen? O Yes O No 10.It turns out that the government funding for public health departments is computed on a formula that is heavily dependent on the number of cases of flu. For efficiency, the government decides to adopt Google flu numbers for this parameter. If you run a public health department, you seek to maximize your funding by asking the public in your county to perform searches for flu. Will this work? O Yes O No
