T score of 99 confidence interval
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. WebConfidence Interval = 3.17 to 3.43; Lastly, the confidence interval at 99% confidence level is 3.17 to 3.43. From the above illustration, the confidence interval of a sample spreads out with the increase in confidence level. Explanation. The formula for the Confidence Interval can be calculated by using the following steps:
