Describing the outcome of the hypothesis test

Reference no: EM13489347

There is some evidence that REM sleep, associated with dreaming, may also play a role in learning and memory processing. For example, Smith and Lapp (9990) found increased REM activity for college students during exam periods. Suppose the REM activity for a sample of n =16 students during the final exam period produced an average score of M =143. Regular REM activity for the college population averages ?= 110 and ? =50. The population distribution is approximately normal. a. Do the data from this sample provide evidence for a significant increase in REM activity during exams? b. Compute Cohen’s d to estimate the size of the effect. c. Write a sentence describing the outcome of the hypothesis test and the measure of effect size as it would appear in a research report.
