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, 43 percent, 21 percent, 22 percent, 7 percent, and 7 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.)
