The frequency polygon to the right shows a distribution of IQ scores. Determine if the following statement is true or false according to the graph.The IQ score that more people had than any other IQ score, and which the scores fall off in a symmetrical manner as the deviation increases or decreases from it, is the IQ score of 85.Is the statement true or false?- True- False**Graph Explanation:**The graph titled "Distribution of IQ Scores" displays a frequency polygon with the following features:- The x-axis represents IQ Scores ranging from 75 to 135.- The y-axis represents the Number of People (Frequency) ranging from 0 to 30.- The peak frequency occurs at an IQ score of 105, indicating it as the most common score.- The distribution shows a symmetrical fall-off from the peak, with frequencies decreasing as the IQ score deviates from 105.
