Question:
A random sample of people who drank coffee in the morning and a random sample of people who did not drink coffee in the morning were asked if they felt sleepy; 38% of coffee-drinkers said they were sleepy and 41% of coffee-drinkers said they were not. You conduct a hypothesis test to determine if the proportions of coffee-drinkers and non-coffee-drinkers who feel sleepy are different. Suppose the p-value you calculated for this hypothesis test is 0.26. Explain the meaning of the p-value being 0.26 in the context of this hypothesis test.
