Researchers wondered whether the size of a person's brain was related to the individual's mental capacity. They selected a sample of 5 females and 5 males and measured their MRI image pixel counts and IQ scores. Females Males MRI IQ MRI IG The data is reported to the right.

Are MRI count and IQ linearly related? Select the correct choice below and, if necessary, fill in the answer box to complete your choice. (Round to three decimal places as needed.) A. Yes, MRI count and IQ are linearly related since the linear correlation coefficient is O B. No. MRI count and IQ are not…

A pediatrician wants to determine the relation that may exist between a child's height and head circumference. She randomly selects 8 children from her practice, measures their height and head circumference and obtains the data shown below.  Height          Head Circumference  27                        17.5 25                        17 26.5                     17.2 25.5                      17 27.75                    17.4 26.25                   17.4  26                         17.1 27.25                    17.4   data table n 3    0.997 4    0.950 5    0.878 6    0.811 7     0.754 8     0.707 9     0.666 10   0.632 11    0.602 12   0.576 13   0.553 14   0.532 15   0.514 16   0.497 17   0.482 18   0.468 19   0.456 20   0.444 21    0.433 22    0.423 23    0.413 24    0.404 25    0.396 26    0.388 27    0.381 28    0.374 29    0.367 30    0.361   compute the linear correlation coefficient between the height and head circumference of a child. r = ____ (round to three decimal places as…
