The box plots show the prices of two different brands of shoes.

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

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
