Question

We’re interested in whether warm milk helps people go to sleep faster. We have a lab with EEG monitors that will provide us with data as to how many minutes elapse before someone falls asleep. (People spend the night in the lab.) In the first experimental condition, participants fall asleep as they usually do, without warm milk. In the second condition, participants drink 6 oz. of warm milk before going to sleep. Data for 5 participants is shown in the table below. Choose the appropriate type of t-test (independent samples or paired samples) and conduct the t-test and hypothesis test. Be sure to show all of your calculations either on your scratch work or in this text box.

DO: Include the t-test value and your hypothesis test conclusion in this text box, not just in your scratch work.
