The stem and leaf plot shows that there were 29 students who took the exam and that nine of them scored between 80 and 89. The range of the grades is not provided, and there are gaps in the data as there are missing stems and leaves. The plot does not show evidence of bimodal data. The stem and leaf plot shows the number of students who scored within each ten-point range. There are 29 students represented on this plot. Therefore, there is no information regarding the range of grades. However, it is clear that 9 students scored between 80 and 89, so option B is correct. There also appears to be no gaps in the data, but there is not enough information to determine if the data is bimodal.
