A reason people give for drinking coffee is “alertness” or “energy”. This could be the case for kids who drink coffee. Or they could be groggier from a lack of sleep due to coffee. We asked n1=50 14-year-old kids who drink coffee if they “felt alert” x1=30 answered yes, we then asked n2=50 kids who don’t drink coffee and x2=20 of the kids answered that they the “felt alert”. We would like to compare these two proportions. . What are the estimated proportions? What are the null and alternative hypothesis? Chapter 7 (see section 7.7 “step 2” and table 7.17) has a rule of thumb for when we can do a specific test in this instance . Do we satisfy this rule of thumb? What will our test statistic be? Perform the test, what do you conclude? Another way we could look at this would be to do a test of association on the 2x2 table constructed from this data (see the HIV IV drug example in the blackboard content directory for 04/06/22->additional information->OR RR and…
