Answer:
The new IQR is 22.
Step-by-step explanation:
We are given the following data of length (in mm) of 12 soybean plants after 3 days of sprouting.
53, 47, 51, 54, 43, 39, 61, 57, 55, 46, 44, 43
Sorted data:
39, 43, 43, 44, 46, 47, 51, 53, 54, 55, 57, 61
Formula:
IQR =
If every measurement is doubled, then, the IQR will also double itself.
Thus,
New IQR =
Thus, the new IQR is 22.
