5-1 Discussion: Z or T Confidence Intervals?

In describing confidence intervals on a mean, z and t intervals are frequently mentioned. How are z and t confidence intervals different? Choose one interval and give an example of how it could be applied within an operations or production environment that is different from those mentioned in the overview. Discuss and share this information with your classmates. In responding to your peers, select responses that use a confidence interval in a scenario that is different from your own. Do you agree with the use of a z or t confidence interval in those examples? Explain your reasoning and consider how confidence intervals could be applied to the final project. Support your initial posts and response posts with scholarly sources cited in APA style.
