how to solve

Use the data set for this question and the next 3 questions: The following scores represent a nurse's assessment (x) and a physician's assessment (y) of the condition of 10 patients at time of admission to a trauma center. X: 18 CO y: 23 CO O Based on the data, we got the Pearson's correlation coefficient r=0.912, and the least squares line: y = 1.21 + 1.08x Select all that are true: (note that this is a multiple selection question with anywhere from 1-4 answers correct) There seems to be a strong, positive correlation between the 2 variables There seems to be a moderate, positive correlation between the 2 variables There seems to be a weak, positive correlation between the 2 variables A very good amount of variation is accounted for
