Answer 3

do you have a rule for determining outliers?

Answer 4

i would say C

Answer 5

if i recall these questions from previous encounters

Q1 to Q3 is 50% of the data, so its range is relevant.

Q1 - (IQR)/2 would define the lowest non outlier

Q3 + (IQR)/2 would define the highest non outlier

Answer 6

this question isnt mine

Answer 7

What is the IQR?

Answer 8

25?

Answer 9

22

Answer 10

oh

Answer 11

68 to 90 is 22

Answer 12

so

68-11 is our lowest non outlier limit
90+11 is our highest non outlier limit

assuming you go by the IQR rule for outliers

Answer 13

68-11=57 & 90+11=101

Answer 14

good, and as we can see

the entire box plot is within 57 to 101, so what is our conclusion?

Answer 15

B?

Answer 16
