Omar counted the number of characters in 60 text messages and recorded the data.
He found that the lower quartile of the data was 31, the median 55, and the upper quartile was 96.
Which is the best estimate of the number of text messages that had between 31 and 55 characters?
the quartile is 1%2F4 or 25% of 60 text messages;
25%2F100=x%2F60
1%2F4=x%2F60
60%2F4=x
x=15
your answer is: C) 15
