He number of years of education of self-employed individuals in the united states has a population mean of 13.6 years and a population standard deviation of 3.0 years. if we survey a random sample of 100 self-employed people to determine the average number of years of education for the sample, what is the standard deviation of the sampling distribution of (the sample mean)

We can solve this problem by using the formula:

s = σ / sqrt(n)

where,

s = standard deviation of the sample

σ = standard deviation of the population = 3 years

n = number of samples = 100

Substituting:

s = 3 years / sqrt (100)

s = 0.3 years                       (ANSWER)

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

answer: no, but if it does it's a obvious pattern.
