Exercise 6.16 (Algo) METHODS AND APPLICATIONS
A survey conducted by a song rating service finds that the percentages of listeners
familiar with \"Poker Face\" by Lady Gaga who would give the song ratings of 5, 4, 3,
2, and 1 are, respectively, 44 percent, 20 percent, 19 percent, 13 percent, and 4
percent. Assign the numerical values 1, 2, 3, 4, and 5 to the (qualitative) ratings 1, 2,
3, 4, and 5 and find an estimate of the probability distribution of x = this song's rating
by a randomly selected listener who is familiar with the song.
Find the expected value of the estimated probability distribution. (Round your
answer to 2 decimal places.)
