given that,

( 6 0 0 2 12 8 6 0 10 0 7 11

5 2 1 10 3 6 6 9 0 3 9 3
12 6 1 4 9 3 9 9 3 7 4 12 )

calculated are,
mean = 5.50
sample variance = 14.94
sample standard deviation = 3.87
sample mean, x =52.4
population size (n)=36
I.
stanadard error = sd/ sqrt(n)
where,
sd = population standard deviation
n = population size
stanadard error = ( 3.87/ sqrt ( 36) )
= 0.645
