Answer
Option D
Step-by-step explanation
For option A:
The spreads for the first 25% of the data distribution for both lakes are equal
Because, the spread for the first 25% for lake Warbler = 7 - 3 = 4
While the spread for the first 25% for lake Mockingbird = 6 - 2 = 4
Hence, option A is true.
For option B
Lake Warbler has a center of distribution of 10, while lake Mockingbird has a center of distribution of 13. Hence, the center of distribution of lake Mockingbird is (13 - 10 = 3 inches) greater than the center of distribution of lake Warbler.
So, option B is true.
For option C
For lake Warbler, the interquartile range = Q3 - Q1 = 15 - 7 = 8
For lake Mockingbird, the interquartile range = Q3 - Q1 = 19 - 6 = 13
So, 8/13 x 100 is about 60%.
Hence, option C is also true
For option D
The data distributions for both lakes are skewed to the left. NOT TRUE
Both lakes' data distributions are skewed to the right.
