(b) describe the relationship between husbands’ and wives’ heights.

(c) which plot shows a stronger correlation? explain your reasoning.

(d) data on heights were originally collected in centimeters, and then converted to inches. does

this conversion a? ect the correlation between husbands’ and wives’ heights?
