The image contains a problem that asks to analyze the student enrollment data for Worcester Public Schools over the last 10-15 years. Here’s a breakdown of the task:

1. **Find the data**: Obtain historical enrollment data for Worcester Public Schools over the past 10-15 years.
   
2. **Construct a scatter plot**: Once the data is obtained, plot the year on the x-axis and the enrollment on the y-axis to create a scatter plot. This will help visualize trends over time.
   
3. **Conjectures about correlation**: Determine if there is a positive, negative, or no correlation between the years and enrollment. This involves analyzing if enrollment has increased, decreased, or remained constant.
   
4. **Write a linear function**: Fit a line (linear regression) to the scatter plot. The general form would be \( y = mx + b \), where:
   - \( y \) represents student enrollment,
   - \( x \) is the year,
   - \( m \) is the slope (rate of change of enrollment per year),
   - \( b \) is the y-intercept (enrollment at year 0).

5. **Predictions for 2024, 2025, and 2030**: Use the linear equation to forecast the enrollment for these specific years by plugging the years into the linear function.

Would you like help finding the enrollment data or constructing the scatter plot and linear function?

### 5 Related Questions:
1. How can the correlation coefficient between year and enrollment be calculated?
2. What factors might influence the trend in school enrollment?
3. How accurate are linear models for predicting future values in real-world situations?
4. How can you interpret the slope of the linear function in the context of school enrollment?
5. What other types of models (besides linear) might better fit enrollment data?

### Tip:
When analyzing trends, always check the residuals (differences between predicted and actual values) to ensure that a linear model is the best fit for the data.

Find the data on the enrollment of the Worcester Public Schools over the last 10-15 years. Construct a scatter plot to represent this data. Any conjectures? What kind of correlation is there between year and student enrollment? What linear function would you write to represent this data? Use your linear function to predict the enrollment in 2024, 2025, and 2030. Any conjectures?
