what percentage of your sample means should be within 1 standard deviation, statistics homework help

Hello I need some help with one of my team assignment. I have question 6. According to the Empirical Rule, what percentage of your sample means should be within 1 standard deviation of the population mean?  Using your computed σ, do your sample means seem to conform to the rule?

Please help me figure this out. I’m so lost.
