A sociologist chose 300 students at random from each of two schools and asked each student how many siblings he or she has. The results are shown in the table below. There are a total of 2,400 students at Lincoln School and 3,300 students at Washington School. What is the median number of siblings for all the students surveyed? |

Answer» 0 Values 1 through 260 will be 0. Values 261 through 450 will be 1. Values 451 through 540 will be 2. Values 541 through 580 will be 3. Values 581 through 600 will be 4. Therefore, both the 300th and 301st values are 1, and hence the median is 1. CHOICES A, C, and D are incorrect and may result from either a calculation error or a conceptual error. |
