Answer:
IQR = 10.
Step-by-step explanation:
15,19,20,25,25,28,29,30,30,35,37,43
There are 12 numbers in the list so the median is the mean of 28 and 29,
The lower quartile is the mean of the 3rd and 4th numbers and the upper quartile is the mean of the 9th and 10th numbers.
Lower quartile = (20+25) / 2 = 22.5.
Upper quartile = (30 + 35) / 2 = 32.5.
So the IQR = 32.5 - 22.5 = 10.
Answer:
10 + 11 = <u><em>21</em></u>
12 + 1 = <u><em>13</em></u>
10 + 10 =<u><em>20</em></u>
20 + 29 = <u><em>49</em></u>
