I am stuck! I have worked out the mean, 102, and the standard deviation which is 9. Now I have no idea what to do. I want to do this is Excel to save time but other answers are very vague and I don't know what to do.
Please help! Give a step by step guide on what to do in Excel and how to plot a chart with the curve. Thanks!
