Write conclusions and results.

Answer 1

Considering three tyes of treatments CBT, Melatonin and Control. If each row shows the Slee latency for a particular experiments, then average can be a indicator of quality of treatment.

A sleep latency of 15 to 20 minute is good indicator treatment.

Minutes	Sleepiness
0–5	Severe
5–10	Troublesome
10–15	Manageable
15–20	Excellent

Average Sleep Latency of CBT=7.9

Average Sleep Latency of Melatonin=12.8

Average Sleep Latency of Control=31.8

Which treatment had the best results?Which treatment had the weakest results?

Melatonin is the best treament as its has average sleep time 12.8 which close to standard range of 15 to 20 while CBT is weakest as lts has lowest sleep latency score.

Null Hypothesis is H0= Average >15

Aletenative is H1=Average <15
