Answer:
Which statement is the most appropriate comparison of the spread?
The correct option is A. The interquartile range (IQR) for brand A, $10, is less than the IQR for brand B, $20.
Explanation:
The given box plots clearly shows the Brand A has interquartile range = 80- 70 =10, while the Brand B has interquartile range = 85 - 65 = 20. Therefore, the option A is correct.
The option B is incorrect because the median of brand A is less than the median of Brand B
The option C is incorrect because the brand A has IQR = 10 and brand B has IQR = 20
The option D is incorrect because the brand A has IQR = 10 and brand B has IQR = 20
