What is the definition of a population proportion?

Back

A population proportion is the ratio of members of a specific category to the total number of members in the population.

Front

What does SRS stand for in statistics?

Back

SRS stands for Simple Random Sample, which is a sampling method where each member of the population has an equal chance of being selected.

If the sample size is 100 for both populations, what is the standard deviation of the difference in sample proportions?

Back

Front

What is the significance of the standard deviation in the context of sampling distributions?

Back

The standard deviation indicates the variability or spread of the sampling distribution; a smaller standard deviation means less variability.

Front

What does it mean if the sampling distribution of the difference in sample proportions is normally distributed?

Back

It means that the distribution of sample proportions will approximate a normal distribution as the sample size increases, according to the Central Limit Theorem.

Front

What is the Central Limit Theorem?

Back

The Central Limit Theorem states that the sampling distribution of the sample mean will be normally distributed if the sample size is sufficiently large, regardless of the population's distribution.

Front

What is the purpose of calculating the difference in sample proportions?

Back

Calculating the difference in sample proportions helps to compare two populations and determine if there is a statistically significant difference between them.
