A scatter plot was constructed on the graph below and a line of best fit was drawn. What is the equation of this line of best fit?
A linear model was constructed for a set of bivariate data.
Given the residual plot shown, what conclusion should be drawn?
Which situation describes a negative correlation?
Which scatter plot shows no correlation?
During their Algebra class on Friday, four students made statements about residual plots. Which two students made accurate statements?
The table shows the largest vertical drops of nine roller coaster in the US and the number of years after 1988 that they were opened.
Create a scatter plot on the graph based on the data provided.
The table shows the largest vertical drops of nine roller coaster in the US and the number of years after 1988 that they were opened.
What is the equation of the line of best fit, rounded to the nearest tenth?
The table shows the largest vertical drops of nine roller coaster in the US and the number of years after 1988 that they were opened.
What is the correlation coefficient of the data shown, rounded to the nearest hundredth?
Megan and Bryce opened a new store called the Donut Pit. Their goal is to reach a profit of $20,000 in their 18th month of business. The table and scatter plot below represent the profit, P, in thousands of dollars, that they made during the first 12 months.
Write the equation for the line of best fit rounded to the nearest tenth.
