For one set of 1000 variables x1, we have a t-stats t1, now we duplicate the variable two times to get 3000 variables: x1, x1, x1, x2, x2, x2, x1000, x1000, x1000 and we have a t-stats t2. what's the relationship between t1 and t2?

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
