AP Statistics Sampling Distributions and Confidence Intervals

Front

What are the conditions for one sample proportion?

Back

The conditions for one sample proportion include random sampling, normality (np and n(1-p) both greater than or equal to 10), and independence/10% Condition n < 0.10N.

Front

What are the conditions for two sample proportions?

Back

The conditions for two sample proportions include independent random samples, normality (np and n(1-p) for both samples greater than or equal to 10), and independence/10% Condition n < 0.10N between samples.

Front

What are the conditions for one sample mean?

Back

The conditions for one sample mean include random sampling, normality (sample size greater than or equal to 30 or population normal), and independence/10% Condition n < 0.10N.

Front

What are the conditions for two sample means?

Back

The conditions for two sample means include independent random samples, normality (sample size greater than or equal to 30 or population normal for both samples), and independence/10% Condition n < 0.10N between samples.

Front

What is the Central Limit Theorem?

Back

The Central Limit Theorem states that the sampling distribution of the sample mean will be approximately normally distributed, regardless of the population distribution, provided the sample size is sufficiently large (usually n >= 30).

Front

What is the 10% Condition?

Back

The 10% Condition states that the sample size should be less than 10% of the population size (n < 0.10N) to ensure independence between observations.

Front

What is the difference between a parameter and a statistic?

Back

A parameter is a numerical value that describes a characteristic of a population, while a statistic is a numerical value that describes a characteristic of a sample.
