4. Look at the relative-frequency table below of the probability distribution for the frequency with which customers buy Items, with discrete random varlable X = "number of items purchased by a
customer."
x P(X = x)
1.02
2.17
3.29
4.27
5.15
6.07
7.03
What is the standard deviation?
o = 1.45
O o = 1.01
O o = 1.67
O o = 1.32
