WebThe formula for the confidence interval is: If n ≥ 30; Confidence Interval = x̄ ± z c (σ/√n) and If n<30;Confidence Interval = x̄ ± t c (S/√n) n = Number of terms. Where, x̄ = Sample Mean. σ = Standard Deviation. z c = Value corresponding to confidence interval in z-table. t c = Value corresponding to confidence interval in t-table.

In practice, we often do not know the value of the population standard deviation ( σ ). WebThe confidence level would increase as a result of a larger interval. Smaller sample sizes result in more variability. To capture the true population mean, we need to have a larger … restaurants in the west bottoms
