Answer:
B. Statistic ± Critical value × Standard error
Step-by-step explanation:
The confidence interval for the mean, for example, is calculated as
![\bar{x}\pm z_{(\alpha)/(2)}\frac{\sigma}{\sqrt[]{n}}](https://img.qammunity.org/2023/formulas/mathematics/college/eswp4vxo0fyfn92qrsazrgh20gnaysipa5.png)
Where x is the statistic, z is the critical value and σ/√n is the standard error, so the general form is
Statistic ± Critical value × Standard error
