SOC: Occupational prestige scores for a sample of fathers and their oldest son and oldest daughter are presented below.

Analyze the relationship between father's and son's prestige and the relationship between father's and daughter's prestige. For each relationship:
a. Draw a scattergram and a freehand regression line.
b. Compute the slope (b) and then find the Y intercept (a).
c. State the least-squares regression line. What prestige score would you predict for a son whose father had a prestige score of 72? What prestige score would you predict for a daughter whose father had a prestige score of 72?
d. Compute r and r 2.
e. Describe the strength and direction of the relationships in a sentence or two. Does the occupational prestige of the father have an impact on his children? Does it have the same impact for daughters as it does for sons?
