(a) assuming that the mcat scores are normally distributed, use table a to find the median and the first and third quartiles of the mcat scores. find the median of the mcat scores. (enter your answer rounded to a whole number.) median= find the first quartile of the mcat scores. (enter your answer rounded to three decimal places.) = find the third quartile of the mcat scores. (enter your answer rounded to three decimal places.) = find the interquartile range of the mcat scores. (enter your answer rounded to three decimal places.) = (b) which interval contains the central 80% of the mcat scores? select the answer choice that approximates this interval. 480 to 520 472 to 528 491.096 to 508.904 486.432 to 513.568
