What is the effect of an oudlier on the confidence interval? O A. The presence of an outler in the original data decreases the value of the sample mean and greatly decreases the sample standard deviation, narmowing the confidenoe interval of an outlier in the original data increases the value of the sample mean and greatly inflates the sample standard deviation, widening the confidence interval of an outler in the original data decreases the value of the sample mean and greaty inflates the sample standard deviation, widaning the confidence interval. data increases the value of the sample mean and greatly decreases the sample standard deviation, narrowing the confidence intervalExplanation / Answer
