1.     Explain how much more or less the standard deviation of sample means was than the population standard deviation. According to the formula for standard deviation of sample means, it should be far less.  (That formula is σ = σ/√n  =  σ/√10  = σ/3.16  )  Does your computed σ  agree with the formula?

 

 

 

 

 

2.     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?
