From A student:
given: n = 40, standard deviation is not known, population of individual observations not normal. does the central limit theorem apply in this case? why or why not?
for an estimation problem, list two ways of reducing the magnitude of sampling error?
What will happen to the magnitude of sampling error if the confidence level is raised all other things remaining the same? justify your answer?
