It seems like you're asking for help with creating and analyzing a scatter plot using some unspecified data related to typing speed, but I don't have access to external graphing tools or the specific data necessary to generate the plot and calculations.
However, I can guide you through the steps to create the scatter plot, analyze it for correlation, and make predictions based on your data.
1. **Create a Scatter Plot:**
- Gather your data points that show the relationship between time (in minutes) and the number of words typed.
- Plot each data point on a graph where the x-axis represents time (minutes) and the y-axis represents the number of words typed.
2. **Draw a Trend Line:**
- After plotting your points, you can draw a line that best fits those points—this is your trend line (you could use a linear regression if you want a more accurate representation).
- The trend line helps in visually determining the general direction (increase or decrease) of your data.
3. **Determine Correlation:**
- If the trend line slopes upwards, there is a positive correlation; more time generally leads to more words typed.
- If it slopes downwards, there’s a negative correlation; more time leads to fewer words typed (though this is unlikely in this context).
- If there’s no discernible slope or pattern, you have negligible or no correlation.
4. **Predictions Based on Correlation:**
- To estimate how many words a student can type in 8 minutes, find where 8 minutes intersects the trend line and project the corresponding value on the y-axis.
- Repeat the process for 15 minutes.
- To find out approximately how long it will take a student to type a 2,500-word essay, determine where 2,500 intersects the trend line and find the corresponding time in minutes on the x-axis.
If you have specific numerical data for the number of words typed in various time increments, I can help you with sample calculations or guide you on how to analyze it further. Please provide the data if available!
