## Question:

Computer optional: Refer to the previous question. Download the Game of Thrones data set from the book website and conduct the following analyses.

**a. **Calculate the hazard ratio of females relative to males in the series.

**b. **Compute an approximate 95% confidence interval for the hazard ratio.

**c. **Carry out a formal test of the null hypothesis of no difference in survival of male and female characters.

**Data from previous question**

Game of Thrones was a television series known for the high frequency of violent acts committed by, and upon, its many characters. Lystad and Brown (2019) tallied the fates of all 359 characters over the complete eight seasons to measure their survival rates and determine the variables predicting mortality. The Kaplan–Meier plot below estimates survival probability of male and female characters in relation to the time (in viewing hours) since they appeared on the show. Shaded areas depict 95% confidence intervals for survival probability. Censored observations (indicated by vertical ticks: “|”) are individuals who hadn’t died but vanished from the show mid-series or at the end of eight seasons after the indicated number of hours since their first appearance.
