1. a) The scatter plot shows a positive linear relationship between height and weight, with points generally increasing from left to right.
b) Using the regression equation, the predicted weight for a person with a height of 58 cm is approximately 106.3 kg.
2. a) The scatter plot shows a negative linear relationship between temperature and number of soft drinks sold, with points generally decreasing from left to right.
b) Using the regression equation, the predicted number of soft drinks sold at 95°F is approximately 473.
3. a) The scatter plot shows a positive linear relationship between diameter and age, with points generally increasing from left to right.
b) Using the regression equation, the estimated age of an oak with a diameter of 18 in is approximately 72 years.
