A statistic from a sampleis used to estimate a parameter of the population. The most likely value for a parameter is the point estimate. Additionally, we can calculate a lower bound and an upper boundfor the estimated parameter. The margin of erroris the difference between the lower and upper bounds from the … See more The following steps are used to calculate a confidence interval: 1. Check the conditions 2.
