28. Age and Weight. The relationship between age and weight is nonlinear, so that linear regression should not be used to test for the relationship. The Centers for Disease Control and Prevention published a case study regarding a particular child, recording the age and weight of this child at various intervals. Assume that the data set represents a random sample. Use the rank correlation test to test for a relationship between age and weight, using level of significance .
