Page 2: Determine the most appropriate hypothesis test to use for the following scenarios 2 3 A team of cognitive psychologists studying the effects of sleep deprivation on short- Page 3: term memory decay had eight participants stay in a sleep lab for two days. Four participants were randomly assigned to a condition in which they were not permitted 5 to sleep during that period, while the other four participants were allowed to sleep when they wanted to. At the end of the two days, the participants completed a short-term memory task that yielded the results in the table that follows.
