1 / 5

On this course, which of the following confidence intervals do we create?

Hint

It is not possible to determine a population statistic with $$100\%$$ confidence from a sample statistic.

2 / 5

If we find that a claim falls within the $$95\%$$ confidence interval, we accept that claim at which level of significance?

Hint

It is not possible to determine a population statistic with $$100\%$$ confidence from a sample statistic.

3 / 5

If a claim does not fall within out confidence interval, that claim must be incorrect.

Hint

A larger sample size represents more of the population.

4 / 5

An increase in the sample size leads to a narrower confidence interval.

Hint

$$\hat{p}$$ is always less than or equal to one.

5 / 5

$$\hat{p}$$ refers to a sample percentage.
