UN Normality Conditions for ANOVA Test Project

I’m working on a statistics discussion question and need a sample draft to help me learn.

For a statistics project, a student gathered data on monthly car insurance premiums paid by students and faculty at a California community college in 2008. She found a fairly strong linear relationship between driving experience and monthly car insurance premiums.

She used the line shown in the scatterplot to summarize the pattern in the data.

Here is the equation of the line:

Predicted monthly car insurance premium = 97 – 1.45 * years of driving experience. I attached the graph you need to use for this disuccion!

Which of the following descriptions are a valid method to predict the monthly car insurance premium for someone who has 12 years of driving experience?

Find 12 on the horizontal axis, trace up to the line and read off the corresponding value on the y-axis. [ Select ] [“valid“, “invalid“]

Substitute 12 into the equation for years and calculate the predicted premium. [ Select ] [“invalid“, “valid“]

Look at the data and find a person who has been driving 12 years. Report the premium paid by that person. [ Select ] [“valid“, “invalid“]
