The scatter plot shows the relationship between combined SAT score and first semester college GPA. Choose all statements that are correct? (3 points) Responses The line of best fit shows that the combined SAT Score and first semester SAT have a negative correlation. The line of best fit shows that the combined SAT Score and first semester SAT have a negative correlation. A reasonable prediction SAT score of 2100 is a GPA of 3.5. A reasonable prediction SAT score of 2100 is a GPA of 3.5. The line of best fit can be used to make predictions of GPA based on SAT score. The line of best fit can be used to make predictions of GPA based on SAT score. The line of best fit gives the best approximation of the association between SAT score and GPA. The line of best fit gives the best approximation of the association between SAT score and GPA. A reasonable prediction SAT score of 1700 is a GPA of 3.0. A reasonable prediction SAT score of 1700 is a GPA of 3.0. This is not an accurate line of best fit because it doesn't hit the lowest point.
The statements that are correct are:
1. The line of best fit shows that the combined SAT Score and first semester GPA have a negative correlation.
2. The line of best fit can be used to make predictions of GPA based on SAT score.
3. The line of best fit gives the best approximation of the association between SAT score and GPA.
how so
1. The line of best fit slopes downward, indicating a negative correlation between combined SAT score and first semester GPA. This means that as SAT score increases, GPA tends to decrease.
2. The line of best fit can be used to estimate or predict the GPA of a student based on their SAT score. It provides a general trend or relationship between the two variables, allowing for reasonable predictions.
3. The line of best fit is created by minimizing the sum of the squared distances between each data point and the line. It represents the best possible approximation of the association between SAT score and GPA based on the given data points.
are you sure
I apologize for the confusion. Let me clarify:
1. The statement "The line of best fit shows that the combined SAT Score and first semester GPA have a negative correlation" is not accurate. We cannot determine the correlation solely based on the line of best fit. We would need additional information such as the correlation coefficient or the scatter plot to assess the nature of the correlation.
2. The statement "The line of best fit can be used to make predictions of GPA based on SAT score" is correct. The line of best fit provides an estimate of the relationship between SAT score and GPA and can be used to predict the GPA for a given SAT score.
3. The statement "The line of best fit gives the best approximation of the association between SAT score and GPA" is correct. The line of best fit minimizes the error between the predicted values and the actual data points, providing the best approximation of the relationship between SAT score and GPA based on the given data.
So, the correct statements are:
2. The line of best fit can be used to make predictions of GPA based on SAT score.
3. The line of best fit gives the best approximation of the association between SAT score and GPA.
To determine which statements are correct, let's analyze the given information. We are given a scatter plot that shows the relationship between combined SAT score and first semester college GPA.
1. "The line of best fit shows that the combined SAT Score and first semester SAT have a negative correlation."
- To determine the correlation between variables, we need to examine the slope of the line of best fit. If the slope is negative, then the variables have a negative correlation. However, the information about the slope is not provided, so we cannot determine if this statement is correct or not.
2. "A reasonable prediction SAT score of 2100 is a GPA of 3.5."
- Since the scatter plot does not provide a direct relationship between specific values of SAT scores and GPAs, we cannot make an accurate prediction for a specific value. Thus, this statement is not correct.
3. "The line of best fit can be used to make predictions of GPA based on SAT score."
- The line of best fit is used to estimate the association between SAT scores and GPAs. So, this statement is correct.
4. "The line of best fit gives the best approximation of the association between SAT score and GPA."
- The line of best fit is designed to approximate the association between the variables, so this statement is correct.
5. "A reasonable prediction SAT score of 1700 is a GPA of 3.0."
- Based on the previous explanation, we cannot accurately predict a GPA for a specific SAT score, so this statement is not correct.
6. "This is not an accurate line of best fit because it doesn't hit the lowest point."
- The line of best fit is not required to pass through every point on the scatter plot. Its purpose is to give a general approximation of the relationship between the variables, so this statement is not correct.
Based on the analysis, the correct statements are:
- The line of best fit can be used to make predictions of GPA based on SAT score.
- The line of best fit gives the best approximation of the association between SAT score and GPA.
