Answer 5

Q1...it is the beginning of the box...not the whiskers, just the box....so Q1 = 10

Answer 15

let me check...
to find outliers...multiply IQR by 1.5
10 * 1.5 = 15
add to Q3....15 + 56 = 71 (anything above 71 is an outlier)
subtract from Q1...46 - 15 = 31 (anything below 31 is an outlier)

answer is A
