Copy and Paste your work from StatCrunch into your Word document submission. Verbally describe the direction and magnitude of the relationship. The scatterplot shows there is a moderate positive relationship between diastolic and systolic blood pressure. 14. Compute the correlation coefficient (Pearson’s r ) in StatCrunch to summarize the relationship for the data presented in Exercise 13. How accurate was your description? Correlation between Question 13 - Diastolic: and Question 13- Systolic: is: 0.90936143

15. Below are Global carbon dioxide concentrations and the measured change in Global temperature (Temperature Anomaly) for an 11-year period in our recent past: YEAR CO 2 Concentration (ppm) Temperature Anomaly (ºC) 1981 339.93 .043 1982 341.13 .022 1983 342.78 .097 1984 344.42 .074 1985 345.90 .091 1986 347.15 .066 1987 348.93 .267 1988 351.48 .155 1989 352.91 .267 1990 354.19 .509 1991 355.59 .430 Using StatCrunch, construct a scatterplot that shows the relationship between the two variables (carbon dioxide concentrations and the measured change in Global temperature). Calculate the r value using StatCrunch. Copy and Paste your work from StatCrunch into your Word document submission. Verbally describe the direction and magnitude of the relationship you find. What does this tell you about Global warming? Correlation between Question 15 - CO2 Concentration (ppm) and Question 15 - Temperature Anomaly (ºC) is: 0.86758467 The scatterplot shows a moderate positive relationship between CO2 concentration and temperature anomaly. This tells me that the increasing amounts of CO2 concentration are having a direct impact on the increasing Global temperature.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
