Question:
A report from Pew Research Center in 2015 found that in a sample of 929 cell phone users ages 13 to 17, the respondents sent and received an average of 67 texts per day while the median number of texts the same group sent and received per day was only 30. What do these statistics tell you about the shape of the distribution of number of texts sent and received each day by this group?
A. Because the median is smaller than the mean, the distribution has mostly larger values with a few smaller values (e.g., it could be skewed to the left).
B. Because the mean is larger than the median, the distribution has mostly smaller values with a few larger values (e.g., it could be skewed to the right).
C. Because the mean and median are different numbers, the distribution must be bimodal.
D. Because the sample size is quite large, the distribution must be fairly bell-shaped.
