In this problem we have two students.
00:02
The first one graduated from a four -year college with an understanding loan of $10 ,116.
00:13
Then we can call it college student and x equals the loan $10 ,116.
00:26
And the average for this college is $8 ,552 with a standard deviation 1 ,852.
00:53
The second student is an university student, university student with y equals $10 ,340 while the average loan equals sorry this was the average but the loan of the student was $12 ,016 dollars with a standard deviation of 2 ,195.
01:42
We want to compare between the two students, which one had a higher debit in relationship to his or her peers.
01:55
Of course, if we want to compare these two individual numbers, this will be bigger.
02:01
But we want to compare how likely this is higher than the average.
02:09
Compared to this which is higher than the average.
02:15
Which one is more high relative to the average here? now we can use the z score to do so.
02:25
Then let's continue by getting the z score here, which equals x minus mu, which is the average divided by sigma, it equals 10 ,000, 100 ,000...
