John said that he scored 150 points on his last Statistics test, which put him at the third quartile (75th percentile) in his class. What does this mean? O John's score of 150 points was lower than 75% of scores when compared to other students in the class. John scored about average on the exam. John's score of 150 points was 75% of all possible points on the exam. John's real score is 112.50 which can be found by multiplying 150 times 75%. O John's score of 150 points was higher than 75% of scores when compared to other students in the class. Question 15 Suppose a distribution has a shape that is skewed left or right. What measure of center would typically be used? standard deviation mean O IQR median Details range
