Question 1

goal of statistical inference

Answer 1

making statements about the underlying population from our available data while making considerations for uncertainty about these generalizations

Question 2

sample data

Answer 2

data from the full population; Want to use sample data to make a generalization about the entire population

Question 3

gold standard for sampling

Answer 3

random selection of the observations in the sample

Question 4

sampling distribution

Answer 4

A distribution of the possible values that a sample statistic can take from repeated samples of the same sample size n when sampling with replacement from the same population

Question 5

properties of sampling distribution

Answer 5

we control: Number of repeated samples to take, The size of the sample, The statistic to calculate for each sample

Question 6

central limit theorem

Answer 6

The more repeated samples do not affect the shape, center, or spread
The more sample size, the more normal for the shape

Making a logical statement and finding the mean of it

Question 8
