10. In a study to investigate whether lack of sleep hurts short-term memory, 10 adults were each tested twice. Both times they studied a list of 30 words for two minutes, and were then asked to recall as many as possible, with a different but comparable list used each time. For one of the two tests they had been without sleep for 24 hours, while for the other they had a normal amount of sleep. The order was randomly assigned. The difference in number of words recalled (with sleep - without sleep) was recorded for each person. The results are given in the table on the right.

Transcribed Image Text:10. In a study to investigate whether lack of sleep hurts short-term memory, 10 adults were each
tested twice. Both times they studied a list of 30 words
for two minutes, and were then asked to recall as many as
possible, with a different but comparable list used each
time. For one of the two tests they had been without
sleep for 24 hours, while for the other they had a normal
amount of sleep. The order was randomly assigned. The
difference in number of words recalled (with sleep –
without sleep) was recorded for each person. The
results are given in the table on the right. Does the lack
of sleep decrease short term memory ? (Use a=0.05).
