Which mean and standart deviantion should I use?

Hi!

I have this plot that was obtained by connecting the occurrence values of a histogram. My teacher asked me to get the probability density function of this plot.

However, I'm having trouble using the normpdf(X,mu,sigma) function. Can anyone tell which values, mu and sigma should I input so that I can have a bell like density function plot?

Thank you for your time

I would be tempted to use the normfit function on the original data instead. If you want the histogram as well, use the histfit function with your original data.
