This is a multi-step question. Be careful! You only get two wrong clicks. Each time you make a wrong click, you'll see a red 'X' on the screen. Agatha needs to find out which month has the highest attendance of visitors to the museum. The spreadsheet shows the monthly attendance for the museum for the last ten years. Agatha has selected the right cells, but she is stuck. Help her find the average of monthly museum visitors for the last ten years. Now, turn that cell red so that the data stands out.
