Answer:

r symbolizes a value of the linear correlation coefficient calculated for from the specific paired sample data in the sample .

ρ is a Spearman's rank correlation coefficient or Spearman's rho that symbolizes a parameter that represents the value of the linear correlation coefficient that would be computed by using ranks all of the paired data in the population for all statistics students.

r is estimated to be  zero​, since there's no correlation between body temperature and head circumference.

Step-by-step explanation:

Spearman's rank correlation coefficient or Spearman's rho is a nonparametric measure of rank correlation
