Find "n" if the Standard Error of M is 4 and the population standard deviation is 16.
1 answer:
Answer:
n = 16
Step-by-step explanation:
Givem that :
Population Standard deviation , σ = 16
Sample size, n =
Standard Error, S. E = 4
To obtain the standard Error, S. E, we use the relation :
S.E = σ / √n
4 = 16 / √n
√n * 4 = 16
Divide both sides by 4
(√n * 4) / 4 = 16 / 4
√n = 4
Square both sides
n = 4²
n = 16
Hence, Sample size = 16
