Twenty different statistics students are randomly selected. For each of them, their body temperature (degrees° C) is measured and their head circumference (cm) is measured.

a. For this sample of paired data, what does r represent, and what does ρ represnts

b. Without doing any research or calculations, estimate the value of r.

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
