a) Calculate the mean and standard deviation of these
five scores.
b) List all possible sets of size 2 that could be chosen
from this class. (There are 5C2 = 10 such sets.)
c) Calculate the mean of each of these sets of 2 scores
and make a dotplot of the sampling distribution of the
sample mean.
and make a dotplot of the sampling distribution of the
sample mean.
d) Calculate the mean and standard deviation of this sam-
pling distribution. How do they compare to those of
pling distribution. How do they compare to those of
the individual scores? Is the sample mean an unbiased
estimator of the population mean?
