Online Python . IDE. 3 4 104% + H FRQ 2 A group of scientists seek to answer the question: Is there a relationship between brain size and Intelligence? A group of 100 volunteers are recruited for study. Each volunteer agrees to have their brain measured and classified as small, medium, or large, They also take an IQ test which classifies them as above or below average intelligence. The table shows the classification of the volunteers. Brain size Small Medium Large Above average 29 20 Below average T 24 12 (a) Calculate the marginal distribution of brain size. Summarize your findings in a sentence. Here is a mosaic plot of the results of the study. 100 90 80 Below Average IQ Above Average IQ Percent 20
