Hello students, today we will discuss about this question.
00:04
In this question we are given that assume you work for a big bank and you determine that the credit card debt amount customers with our understanding balances, outstanding balances on their accounts has a normal distribution and the mean of the distribution is so here mean that is equals to $1 ,000, and the population standard deviation.
00:32
So here we are given that the population standard deviation that is equals to dollar 4 ,000.
00:41
Now if a random customer with an outstanding balance on his account approaches you, you what is the probability that the customer has more than 15 ,000 in credit card debt.
00:56
So here we need to find the probability of the customer.
01:03
Customer has more than $115 ,000 in credit card.
01:14
So that is equal to we need to find here the probability x is greater than $15 ,000 is equals to question mark.
01:22
So here first of all, we can write here let x that be a credit card debt of customer balance...
