Problem
"PARADE"is the Sunday newspaper magazine supplementing the Sunday or weekend edition of some 500 daily newspapers in the United States of America. An important yearly feature is an article providing information on some 120-150 "randomly" selected US citizens, indicating their profession, hometown and state, and their yearly earnings. The Parade2005 data contain the 2005 version, amended by a variable indicating celebrity status (motivated by substantial oversampling of celebrities in these data). For the Parade2005 data:
(a) Determine the mean earnings in California. Explain the result.
(b) Determine the number of individuals residing in Idaho. (What does this say about the data set?)
(c) Determine the mean and the median earnings of celebrities. Comment.
(d) Obtain boxplots of log(earnings) stratified by celebrity. Comment.
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
