Question

5-81. Scientists hypothesized that dietary fiber would impact the blood cholesterol level of college students. They collected data and found r = -0.45 with a scattered residual plot. Interpret the scientists' findings in context. Hint: r stands for correlation coefficient)​

Answer 1

Step-by-step explanation:

It shows that the content of dietary fiber is negatively correlated to the blood cholesterol of college student, as the correlation coefficient is negative. However, the r=-0.45 shows the two factors are lowly correlated (absolute value of r between 0.3 and 0.5)
