The sample size e) f) Number of classes the researcher can use to summarize his findings (hint: use 2>n) g) Can the researcher apply central limit theorem? (yes /no) Explain h) What is the shape of this sampling distribution? (normal / approximately normal) (hint: the researcher has no prior knowledge about the population distribution)
Homework Answers
E) sample size = n =30
F) 2k > n
25 > 30
K = 5
G) researcher can not apply
Because we do not have sample standard deviation.
H) this is approximately normal
