Hi,

A population has a standard deviation σ of 27 units. (Give your answers correct to two decimal places.)

(a) Find the standard error for the mean if n = 10. SE =  

(b) Find the standard error for the mean if n = 42. SE =  

(c) Find the standard error for the mean if n = 76. SE = 

Caculator will make short work of Your answers (round to 2 decimal places)
