1. This study assessed the relationship between the distance (miles) and the severity of fire damage (a severity index marked by x1000). We want to see if we can predict the severity of the fire based on how far away the company is from the fire. Please use the accompanying data to answer the following questions.

Copy and paste the scatterplot as your answer. 2. Fit a linear regression model to sleep duration and driving errors. Copy and paste the Model Summary, ANOVA, and Coefficients table as your answer. 3. What is the value of the correlation coefficient between sleep duration and driving errors? 4. Is the regression analysis statistically significant? What is the test statistic, degrees of freedom, and p-value that supports your answer? 5. State the regression equation. 6. We are 95% confident that the true population slope parameter will fall between which two…
