Problem According to an article in Travel and Leisure, every person in a small study of sleep during vacation was found to sleep longer than average during the first vacation night.1 Suppose that the number of additional hours slept in the first night of a vacation, over the person's average number slept per night, is given by the following probability distribution:
x
P(x)
0
0.01
1
0.09
2
0.30
3
0.20
4
5
0.10
