Question

the table shows the ages and weights of babies at a hospital. newborn class weight check age (weeks) 1 2 3 3 4 4 6 8 9 9 weight (lbs) 7.5 7.25 8.2 7.95 8.0 9.75 9.25 8.9 9.85 10.0 what is the correlation between age and weight as shown in the table? none positive negative constant

Explanation:

To determine the correlation, we analyze the trend between age (in weeks) and weight (in lbs). As the age of the babies increases (from 1 week to 9 weeks), the weight generally increases (e.g., at 1 week weight is 7.5 lbs, at 9 weeks it's 10.0 lbs; most data points show an upward trend). A positive correlation exists when an increase in one variable (age) is associated with an increase in the other variable (weight). There's no constant weight (values vary) and no negative correlation (weight doesn't decrease with increasing age). So the correlation is positive.

Answer:

positive
