Okay; I've typed out the text in your too-small image, found and uploaded a legible "distribution" picture for you, and updated your subject line from the name of your image to a preview of the posted exercise. Now we need to know what you've done and where you're getting bogged down.

You can see from the picture where the top 2% lies. You can see how the percentage is related to standard deviations from the mean. You've been given a mean and a standard deviation. You can see from the picture how many times to add. And... then what? Where are you stuck?

Please be complete. Thank you!
