QUESTION:
Texts or calls? Refer to Exercise 91. A boxplot of the difference (texts calls) in the number of texts and calls for each student is shown below.
(a) Do these data support the claim in the article about texting versus calling? Justify your answer with appropriate evidence.
(b) Can we draw any conclusion about the preferences of all students in the school based on the data from Mr. Williams’s statistics class? Why or why not?
ANSWER:
Step 1 of 2
(a)
From the given boxplot, we can say that if the difference is positive then text messages are more than the calls. And we know that the central box of a boxplot is drawn from the first quartile to the third quartile. So, only 25% difference is below 0 and 75% of the difference is above 0, which supports the article’s conclusion.
