Find the z-score that has 37.83% of the distribution’s area to the right. Method 1: Use the z-table. The z table shows the area to the left of various z-scores. Thus, if we know the area to the right is .3783 then the area to the left is 1 – .3783 = .6217

WebA skewed distribution occurs when one tail is longer than the other. Skewness defines the asymmetry of a distribution. Unlike the familiar normal distribution with its bell-shaped … In probability theory and statistics, skewness is a measure of the asymmetry of the probability distribution of a real-valued random variable about its mean. The skewness value can be positive, zero, negative, or undefined. For a unimodal distribution, negative skew commonly indicates that the tail is on the left side of the distribution, and positive skew indicates that the tail is on th… chewy open interviewshttp://courses.atlas.illinois.edu/spring2024/STAT200/pnormal.html goodyear assurance maxlife 235/55/19
