Thanks /u/Pandanleaves for helping me in the last thread, I'm still having a little trouble with this question so I'm going to post here as this thread has replaced the one I posted in.

Basically now I know what to put for everything except the average, and I'm still a little confused on how to do the subsequent questions. This is how the answer key for my previous attempt showed how to do this question, but with different numbers. Any help appreciated!

Hi

I have some homework for my finance class to do online. One of the questions wants me to use the NORMDIST function in Excel, unfortunately my prof never went over how to use Excel. I watched this video to try and figure it out, but I don't know which number to use for x, mean, and cumulative (the video said cumulative should be 1?). Anyway, this is the question; any help is appreciated!

> Suppose the returns on long-term corporate bonds are normally distributed. Suppose the historical average annual return for the long-term corporate bond was 7.6 percent and the standard deviation was 8.6 percent. What is the approximate probability that your return on these bonds will be less than –9.3 percent in a given year? Use the NORMDIST function in Excel(R) to answer this question. (Do not round intermediate calculations and round your final answer to 2 decimal places. (e.g., 32.16)) > > >What range of returns would you expect to see 95 percent of the time? (Enter your answers for the range from lowest to highest. Negative amounts should be indicated by a minus sign. Do not round intermediate calculations and round your final answers to 2 decimal places. (e.g., 32.16)) > > > What range would you expect to see 99 percent of the time? (Enter your answers for the range from lowest to highest. Negative amounts should be indicated by a minus sign. Do not round intermediate calculations and round your final answers to 2 decimal places. (e.g., 32.16))

I can't seem to get the formatting right on the quote, sorry for the wall of text!
