Statistics

7.1 Sampling
Variability,
Describing Sampling
Distributions
pg. 417-428
Learning Targets

Distinguish between a parameter
and a statistic.
Pg. 428 (1, 3,
5, 7)

Understand the definition of a
sampling distribution.
Distinguish between population
distribution, sampling distribution,
and the distribution of sample data.
Determine whether a statistic is an
unbiased estimator of a population
parameter.
Understand the relationship
between sample size and the
variability of an estimator.
Find the mean and standard
deviation of the sampling
distribution of a sample proportion
p for an SRS of size n from a
population having proportion p of
successes.
Check whether the 10% and
Normal conditions are met in a
given setting.
Use Normal approximation to
calculate probabilities involving p.
Use the sampling distribution of p
to evaluate a claim about a
population proportion.
Find the mean and standard
deviation of the sampling
distribution of a sample mean 𝑥̅
from an SRS of size n.
Calculate probabilities involving a
sample mean 𝑥̅ when the
population distribution is Normal.
Explain how the shape of the
sampling distribution of 𝑥̅ is
related to the shape of the
population distribution.
Use the central limit theorem to
help find probabilities involving a
sample mean 𝑥̅ .
