Rem (rapid eye movement) sleep is sleep during which most dreams occur. each night a person has both rem and non-rem sleep. however, it is thought that children have more rem sleep than adults†. assume that rem sleep time is normally distributed for both children and adults. a random sample of n1 = 11 children (9 years old) showed that they had an average rem sleep time of x1 = 2.6 hours per night. from previous studies, it is known that σ1 = 0.6 hour. another random sample of n2 = 11 adults showed that they had an average rem sleep time of x2 = 1.80 hours per night. previous studies show that σ2 = 0.9 hour. do these data indicate that, on average, children tend to have more rem sleep than adults? use a 1% level of significance.

the correct answer is a) they believe they have a "just cause."

islamic terrorists justify their violent actions because they believe they have a "just cause."

every act of terrorism of islamic sects is done “in the name of allah”. that justifies their actions. islam people who commit those terrorist attacks are not afraid to die. that is why the attacks have horrible consequences. they know they are going to die and they are proud to do it because it is in the name of allah, so it is justified and is for a “good cause.”

since the very beginning of the conflict with israel, islam is fighting a “sacred war”, respecting the words stated in the qur’an. they fight against the domination of the western countries and to defend their occupied territories.
