A researcher is studying the factors related to the popularity of new music artists. In particular, she is interested in assessing the extent to which the number of albums sold (thousands) is explained by the number of YouTube views (millions) the artists currently have, their number of Facebook fans (millions), and the number of weeks they did not make the coveted JJ's Top 50 list in the last 12 months. A random sample of 58 popular new artists was collected (see partial data in the following table). New You Tube views Facebook fans Weeks off Albums sold Artist (millions) (millions) Top 50 ('000) 284.97 7.22 25.9 65.511 2 66.11 18.61 23.7 27.179 3 47.92 5.07 29.5 12.902 . . . . . .

If the artist has 20 million YouTube views and has successfully made JJ's Top 50 list 42.5% of the time in the last 12 months, how many Facebook fans (in thousands) does the artist have?
