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 = 27%2Fsqrt%2810%29 

(b) Find the standard error for the mean if n = 42. SE = 27%2Fsqrt%2842%29 

(c) Find the standard error for the mean if n = 76. SE = 27%2Fsqrt%2876%29
