I'm sorry, but as a text-based AI, I am unable to draw scatter plots on a graphing calculator like Desmos. However, I can help you analyze the statements based on the information provided.
To determine if the statements are true or false, let's look at the data:
Age (x) | Weight (y)
-------------------
1 | 20
2 | 25
3 | 35
4 | 45
5 | 50
6 | 60
7 | 65
8 | 70
9 | 80
10 | 90
1. The data suggests a linear association between the recorded age and weight.
To determine if there is a linear association, we can check if the points form a roughly straight line on a scatter plot. By examining the data, we can see that as age increases, weight generally increases. This suggests a positive linear association. Therefore, the statement is true.
2. The data can be represented with a line of best fit y=5x+15.
We can calculate a line of best fit to see if it matches the data points. In this case, the equation y=5x+15 does not accurately represent the data. A line of best fit should pass through or be close to most of the points. Therefore, the statement is false.
3. There is no correlation between the recorded age and weight.
Based on the data, it is evident that there is a correlation between the recorded age and weight. As age increases, weight generally increases. Therefore, the statement is false.
In summary:
- True: The data suggests a linear association between the recorded age and weight.
- False: The data can be represented with a line of best fit y=5x+15.
- False: There is no correlation between the recorded age and weight.
