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 51 popular new artists was collected (see partial data in the following table). New YouTubeviews Facebookfans Weeks off Albums sold Artist (millions) (millions) Top 50 ('000) 1 124.47 13.85 20.9 42.641 2 81.44 1.43 32.8 14.721 3 146.23 18.08 20.5 53.079 The researcher used software to generate a multiple linear regression output for the data. The results are shown below (some values are missing). a) Determine the missing values. Report answers accurate to at least 5 decimal places where necessary. Do not round intermediate results.

Round percent to 1 decimal place (3) Use the regression coefficients from the output to estimate the number of albums sold (units) for a new artist with 21 million YouTube views, having 2,587,841 Facebook fans, and with exactly 2.4 months off JJ's Top 50 list. [:] d) Suppose the regression equation from the output is used to predict the number of albums sold by a new artist to be 28,120. If the artist has 103 million YouTube views and has successfully made JJ's Top 50 list 55% of the time in the last 12 months, how many Facebook fans (in thousands) does the artist have? Round to the nearest thousand. [j
