2. A team of cognitive psychologists studying the effects of sleep deprivation on short-term memory decay had ten participants stay in a sleep lab for two days. Five participants were randomly assigned to a condition in which they were not permitted to sleep during that period, while the other five 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. Using the .05 significance level, did sleep deprivation reduce short-term memory? Use the five steps of hypothesis testing. Step 1: Null and Research Hypothesis Step 2: Create your comparison distribution, including drawing out the distribution. Mean Number of [etters Remembered Sleep Deprived Normal Sleep Y 8 I} 10 7 Step 3: Determine your Critical Values Step 4: Calculate your t Score Step 5: Decision Step 6: Calculate Effect Size
