Question 2 Data were measured on 70 girls in the Berkley Guidance study which enrolled children born between January 1928 and June 1929 in Berkley (CA, USA), and then measured them periodically until age eighteen. The data are in BGSGIRLS.SAV (or bgsgirls]. txt). The recorded variables are: HT2 Height (cm) at age 2 years HT9 Height (cm) at age 9 years HT18 Height (cm) at age 18 years WT18 Weight (kg) at age 18 years SOMA Somatotype, a 1 to 7 scale of body type. Obtain a scatterplot matrix. Try to insert scales on the x- and y-axes. Use the scatterplot matrix to answer most of the following questions: a) Describe how HT18 behaves as a function of (i) HT2 (ii) HT9 (iii) WT18 b) Describe the relationships between SOMA and the remaining variables. c) Explain why, in all the graphs which involve SOMA, the points lie in either horizontal or vertical lines. d) Did the girl who was tallest at age 2 remain the tallest at ages 9 and 18? Indicate this data point (by hand) in the relevant plots. e) What was the tallest girl at age 18's weight at age 18 (approximately)? () Where did her weight rank? (rank 1 = heaviest, ..., rank 70 = lightest) g) Indicate another outlying point in the graphs. In what way is this girl unusual? h) How many girls were of Somatotype 6? For the questions you cannot answer using the scatterplot matrix, produce the appropriate scatterplot to assist you in answering the
