Participants in a study took the drug LSD and then took a math test. The concentration, C, of LSD in a participant's tissue is measured in ppm (parts per million). The test score, T is measured in points. 100.00 90.00 80.00 70.00 60.00 Math Test Score (Points) 50.00 40.00 30.00 20.00 10.00 0.00 0.00 1.00 2.00 3.00 4.00 5.00 6.00 7.00 LSD Concentration (ppm) The equation of the trend line is T = 89.12 - 9.01C Part 1 Based on the scatterplot, what kind of correlation (if any) exists between the concentration of LSD in a participant's tissue and their math test score? There is no correlation between LSD concentration and test score. O There is a negative correlation between LSD concentration and test score. O There is a positive correlation between LSD concentration and test score. Part 2 What is the initial value of the trend line's equation? Include units. ---Select-- What is the practical interpretation of the initial value? O A person's math score is expected to decrease by 9.01 points per ppm of LSD. O A person who has a concentration of 0 ppm of LSD in their tissue has an expected math score of 89.12 points. O A person who has a math score of 0 points has an expected concentration of 89.12 ppm of LSD in their tissue. A person's concentration of LSD is expected to decrease by 9.01 ppm per point on their math test.What is the growt rate of the trend line's equation? Include units. Hint: Look at the frendlr'ne. What Sign do you expect for the growth rate? : 1What is the practical interpretation of the growth rate? 0 A person who has a concentration of El ppm of LSD in their tissue has an expected math score of 89.12 points. 0 A person's math score is expected to decrease by 9.01 points per ppm of LSD. O A person's concentration of LSD is expected to decrease by 9.01 ppm per point on their math test. 0 A person who has a math score oft] points has an expected concentration of 89.12 ppm of LSD in their tissue. ElPaItEl Predict the test score of a person who has an LSD concentration of5 ppm. Include units. Do not round. : Did 1,rou just interpolate or extrapolate? O interpolate O extrapolate If a person has a test score of 70 points, what is their expected concentration of LSD? Round your result to two decimal places
