Need these two questions done ASAP Statistics completed in a hour

Attached is the work that I have completed already. please state you answers in excel and in Word formats. 

1.     According to the Empirical Rule, what percentage of your sample means should be within 2 standard deviations of the population mean?  Again, do your sample means seem to conform to the rule?

2.     You used the Empirical Rule because it really gives us more information (and because I asked you to), but truthfully you should have used Chebyshev’s Theorem.  Even though Chebyshev’s doesn’t tell us much, why should you have used that one instead?
