In this question, we are going to focus on the given study about the death rate for people who tend to sleep 6 to 7 hours per night and their comparison with the people who are sleeping more.
00:13
So firstly we can say that the given information include death rate and now we can say that it is including death rate of all those people who sleep about 6 hours to 7 hours per night and this is lower than death rate.
00:30
Whose sleep is more than 8 hours per night.
00:33
Now here we can say that 1 .1 millions of observations came from a random survey of 30 to 108 years old.
00:46
So it can be written over here like this.
00:49
And now we can say that third given information is each person was dragged for four years.
00:57
So it can be written over here as such.
01:01
Now we will discuss for the other given information and the other information is that death rate for those who sleep for six hour are similarly calculated.
01:14
So we can write death rates for six hour of sleep is also calculated similarly.
01:24
So with these given information we can conclude here.
01:28
Let us write the conclusion.
01:30
And it is basically going to be that the survey does not include the reason why, let's write survey does not include the reason...
