5 6 7 8 2 5 Given that: the value 2 occurs 10% of the time, the value 3 occurs 13% of the time, the value 4 did not show up in the first seven trials, but it is known to occur 15% of the time, the value 5 occurs 9% of the time, the value 6 occurs 12% of the time, the value 7 occurs 16% of the time, the value 8 occurs 14% of the time, the value 9 occurs 11% of the time, what are the mean and standard deviation of X? (Remember that these are the long- run mean and the long-run standard deviation.) Enter your answers in the appropriate blanks below.
