Daughter Sarah sometimes plays timed games on Sporcle, a trivia quizzing website. She suspects that, on average, as her accuracy (% correct on a quiz) increases, the time left on the timer (in seconds) decreases. In other words, if she takes more time on a quiz, she gets more correct. She'd like to assess her theory. Small sample binomial test One-sample z-test for one population proportion One-sample t-test for one population mean One sample t-test for the population mean of differences (paired data) Two-sample t-test for the difference in two population means One sample t-test for the population slope of a regression line Chi-squared test of goodness of fit Chi-squared test of independence

Question
One important aspect in statistics is to understand which statistical methods or procedures are appropriate to use to address the research problem or question of interest. A family (Rick, Gail, and daughters Emily, Sarah, and Mary Anne) has played board games regularly for multiple years. Because they are good statisticians, they record many variables about their games for future analysis. Assume that we have an appropriate random sample for each scenario. For the following scenarios, indicate which type of hypothesis test should be performed.
