If the distribution for a statistic follows the shape of a normal distribution with standard error SE, we find a confidence interval
for the parameter using
Sample Statistic + z* · SE
where z* is chosen so that the area between –z* and +z* in the standard normal distribution is the desired level of confidence.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F6c70a8a2-c81a-48ac-ab68-b2834939c6b9%2F9de75c6a-f084-4489-9a20-24db61d0042e%2Fke2xijo_processed.png&w=3840&q=75)
