The weights of men in a particular age group have mean ? = 176 pounds and standard deviation ? = 36 pounds.

(a) For randomly selected samples of n = 36 men, what is the standard deviation, s.d., of the sampling distribution of possible sample means?

s.d.(x) =

(b) For randomly selected samples of n = 144 men, what is the standard deviation, s.d., of the sampling distribution of possible sample means?

s.d.(x)

=

(c) In general, how does increasing the sample size affect the standard deviation of the sampling distribution of possible sample means? Parts (a) and (b) provide a hint.

Increasing the sample size the value of the standard deviation of the sampling distribution of the sample mean. A fourfold increase in sample size multiplies the standard deviation by a factor of .
