Question: A random sample of n observations is selected from a population with standard deviation = 1. Calculate the standard error of the mean (SE)

A random sample of n observations is selected from a population with standard deviation σ = 1. Calculate the standard error of the mean (SE) for these values of n:
a. n = 1
b. n = 2
c. n = 4
d. n = 9
e. n = 16
f. n = 25
g. n = 100
Plot the standard error of the mean (SE) versus the sample size n and connect the points with a smooth curve. What is the effect of increasing the sample size on the standard error?
