Question

Chuck works at the BuyMore where people can bring in broken computers. When a customer enters the store there is a good chance he will not be paid anything from helping them. But sometimes there is a chance he will be paid to work on their computer. The probability of each amount from a random customer is given in the following table:

Job payment	$13	$90	$300	$1,400
Probaiblity	0.39	0.1	0.06	0.01

When the next person walks into the BuyMore, how much money can Chuck expect to get from them on average?
Answer to two decimals

What is the probability he will get less than $160 from a random customer?
Answer to four decimals

What is the standard deviation for the payments from the customers?
Answer to two decimals

What is the median job payment amount?
Answer to two decimals

Definition Definition Middle value of a data set. The median divides a data set into two halves, and it also called the 50th percentile. The median is much less affected by outliers and skewed data than the mean. If the number of elements in a dataset is odd, then the middlemost element of the data arranged in ascending or descending order is the median. If the number of elements in the dataset is even, the average of the two central elements of the arranged data is the median of the set. For example, if a dataset has five items—12, 13, 21, 27, 31—the median is the third item in ascending order, or 21. If a dataset has six items—12, 13, 21, 27, 31, 33—the median is the average of the third (21) and fourth (27) items. It is calculated as follows: (21 + 27) / 2 = 24.
