the table and graph shows the relationship between height (cm), x, and weight (kg), y. which statements are correct? a the value of r is about 0.67. b this is a strong positive correlation. c the equation 0.72539x + 53.05434 models the data. d there is a linear relationship between height and weight. e there is a tendency for high weights to be associated with high heights.
Answer
Explanation:
Step1: Analyze scatter - plot pattern
By observing the scatter - plot of height and weight data, we can see that as height increases, weight generally increases. This indicates a positive relationship.
Step2: Evaluate correlation strength
A correlation coefficient (r) close to 1 represents a strong positive correlation. Just by looking at the scatter - plot, we can see that the points follow a somewhat linear upward - sloping trend, but not perfectly. A value of (r\approx0.67) is reasonable for this kind of moderately strong positive relationship.
Step3: Consider linear model
The general form of a linear regression model is (y = mx + b). If there is a linear relationship between two variables, a linear equation can be used to model the data. Given the upward - sloping trend of the scatter - plot, a linear model like (y=0.72539x + 53.05434) is a possible fit.
Step4: Confirm linear relationship
The scatter - plot shows that the points roughly form a linear pattern, so there is a linear relationship between height and weight.
Step5: Identify association
Since the points show an upward - sloping trend, high weights are associated with high heights.
Answer:
A. The value of (r) is about (0.67). B. This is a strong positive correlation. C. The equation (0.72539x + 53.05434) models the data. D. There is a linear relationship between height and weight. E. There is a tendency for high weights to be associated with high heights.
