This packet will help you review a mix of questions from each unit. Remember to check the answer key and ask questions! In the research department of a university, 300 mice were timed as they each ran through a maze. The results are shown in the cumulative frequency diagram opposite. (a) How many mice complete the maze in less than 10 seconds? (b) Estimate the median time. (c) Another way of showing the results is the frequency table below.
