Nthe ideal normal curve, 95% of the population falls within standard deviation(s) of the mean. a. one b. two c. three d. four

In the diagram, points d and e are marked by drawing arcs of equal size centered at b such that the arcs intersect ba and bc. then, intersecting arcs of equal size are drawn centered at points d and e. point p is located at the intersection of these arcs. based on this construction, m , and m
